. A student will then take several years to refine and polish the basic idea to bring it to a shape in which it can be sent to a conference or journal for publication. Here again, reviewers might have a host of concerns and comments that need to be addressed. At the end of his Ph.D, a person is expected to know almost everything about the little tiny area that he has been working in, and to also be a very technically proficient person. Ph.D is also a license to teach, conduct research, and join academics.

This is often not the case. Additionally, a lot of part-time candidates have the perception that their job experience substitutes for good interview performance. This is also not the case. In the age of RTI, we need to maintain transparency and fairness. After shortlisting, the only thing that counts is performance on the interview table. Discussing prior experience, professional contributions, and details of any prior research work, is pointless. All the candidates are on a level playing field, and they need to be able to answer the questions that are asked to them. This is the only thing that counts.

Common computer science interview questions: What to expect

Landing a computer science job requires preparation. Beyond earning your degree , searching for jobs, and submitting applications, the computer science hiring process usually involves several rounds of interviews. You'll face general questions, behavioral and situational questions, and technical questions.

Fortunately, you can prepare for these questions in advance — but only if you know what to expect. Before your interview, you need to know the most common computer science interview questions.

What to expect when interviewing for a computer science role

Professionals in all career stages must get through the interview process to land in-demand computer science jobs .

But what should you expect during a tech interview? And what kinds of computer science interview questions will the interviewer ask?

Most technical jobs use a multi-round interview process.

Behavioral and situational interview questions

Behavioral and situational questions assess how you handle different situations at work. These questions often start with "Tell me about a time when …" or "Describe a situation where …"

Interviewers ask behavioral and situational interview questions to learn how you approach conflict, work with others, and solve complex tasks.

During an interview, you might struggle to present focused, relevant answers to these open-ended questions. Before the interview, prepare a list of examples to draw from when answering behavioral and situational interview questions.

For example, list your professional accomplishments. Describe times you learned from a mistake, solved a complex task, or worked well in a larger team. You can also list examples of you managing projects, taking on leadership roles, and thinking creatively. Draw from these stories during interviews.

These questions may come up at any phase of the interview process.

How would coworkers describe you? How would your supervisor describe you?

Think about a time you achieved a goal. What steps did you take to accomplish your goal?

Give me an example of a time you made a mistake at work. How did you address the mistake?

Tell me about a time you took on a leadership role on a team. What did you learn from the experience?

Describe a situation where you resolved a technical problem.

Tell me about a time when you solved a complex task. What steps did you take?

Describe a situation where you disagreed with someone on your team.

Tell me about a project that failed. What did you do next?

Give me an example of when you solved a problem with an unusual approach.

Think about a time you gave bad news to your supervisor. How did you approach the situation?

General interview questions

Many tech interviews start with general interview questions — and they come up throughout the interview process, too.

Make sure you have solid answers to open-ended questions like "Tell me about yourself." Practice describing your background, qualifications, and prior experience.

Use your answers to these questions to show interest in the company and the position. Tie your answers back to the job description. Finally, express enthusiasm through your answers.

Tell me about yourself.

What is one of your most significant accomplishments?

What's your background in this field?

What programming languages do you prefer to work in?

What's one of your greatest strengths?

What's one of your greatest weaknesses?

What are some of your short-term and long-term professional goals?

Where would you like to be professionally in five years?

Why are you interested in this position?

Why should we hire you for this role?

In conclusion

Whether you're up for your first tech job or you're an experienced worker, the interview process might make you nervous.

Researching computer science interview questions and preparing answers will boost your confidence and help you get to the next interview stage. Knowing what questions to expect might even land you a job offer.

Want to share your interview experience.

Updated: Nov 06, 2023

Here I’m sharing my experience attending written tests and interviews for a Ph.D. in Computer Science at IIT Bombay

Questions they asked to solve in 3 hours. There were two panel interviews.

Interview Questions on Formal Methods and Theory of Computation

There were eight questions in the written test that you have to attempt.

1. There were ten basic “True”/”False” objective questions based on the closure properties of Recursively Enumerable languages and Recursive Languages. (10 marks)

For example,

There can be a language that is recursive but not recursively enumerable.

2. Given an NFA we have to make the final states to be non-final and vice versa. There were 4 TRUE/FALSE type questions related to the language of the NFA.

3. Given a propositional logic with only two variables “p” and “q” with explicitly two outcomes only ie true or false. Count and tell the total number of truth tables possible for this. You have to prove and show the result. (10 marks)

4. Given a quantifier. You have to translate it and give a model based on that. You can figure out if you have done the basics of mathematical logic and solved all GATE previous year’s questions. (10 marks)

5. Write a program with four inputs a , b , c , d such that a>b and c>d . Print the outcome such that both overlap.

6. Given a language aaabbaab that belongs to an NFA machine. Now two other strings are given. You have to show whether they also belong to the same NFA or not.

7. A CFG is given.

Make the DPDA for this grammar if any DPDA is possible. (10 marks)

8. (01)* make the DFA of it and have to tell the number of equivalence classes for this. Three relations were there based on the strings of this DFA. Tell the equivalence classes of each relation.

Hint: Check this DFA example for practice .

Later, I was asked for another interview and written test with a different panel. Here are some of the Interview Questions for a Ph.D. Program in Computer Science at IIT Bombay, as I’m able to remember.

Written Test- Systems Software Questions

In this interview, you will be tested with System Software questions.

1. Programming questions based on GCD. Fill in the blanks with code.

Solution: Program to find the GCD of two numbers .

2. Pattern questions on programming fill in the blanks.

3. Computer networks question about finding the total subnets possible where CIDR notation of IP address given. One question from DNS. One basic congestion control question is to find the total number of RTTs. These are GATE-related questions.

4. One conceptual question based on the page table.

5. Question on file systems from operating systems.

Related: File system is one of the important topics from Operating System .

6. True and false statements from COA. Mostly from Pipelining and Cache Mapping.

7. One programming question. I’m unable to remember it now.

Solution: You can be asked for any programming questions. For practice, check the list of interview coding questions .

8. Stop and wait for the protocol question where you have to find throughput and in the second part have to find the window size.

Deep learning has become a hot topic in recent years due to its potential applications in fields such as artificial intelligence, machine learning, and computer vision. In order to train a deep learning network, it is first necessary to create a model. A model is a representation of the data that the network is expected to learn from.

21. What are the different OOPS principles?

OOPS, principles are a set of rules and guidelines that organizations can use to ensure that their software is as bug-free as possible. The OOPS principles are:

Open source- All software should be released under an open-source license, such as the GNU General Public License (GPL) or the Apache License.
Patent- All software should be released with a patent waiver, such as the USPTO's Patent Promise or the EU's EPO.
Quality- All software should be developed using quality-assured tools and practices, such as unit testing and code reviews.
Simplicity- All software should be easy to understand and maintain, and should not require complex configuration or customization.
Reuse- All software should be reusable so that it can be adapted to new needs without requiring a complete rewrite.

22. Explain the access modifiers?

Access modifiers are a way of specifying which users have access to a resource. Access modifiers are often used to control access to data, files, or other resources. For example, a database might allow only certain users to see the data. Or, a file might be locked down so that only the owner can see it.

23. What do you mean by destructor?

A destructor is a function that is called when an object is destroyed. A destructor is a way to clean up after an object has been destroyed. When an object is destroyed, the memory associated with the object is released. When an object is created, the memory associated with the object is allocated. The destructor is called when the memory associated with the object is no longer needed. The destructor frees up the memory associated with the object and releases it into the environment. When an object is destroyed, it can be very difficult to find out why an object was destroyed.

24. What are the Layers of the OSI Model?

The OSI model is a system-level networking model that describes the topology of a network. The model consists of seven layers: Physical, Data Link, Transport, Network, Application, and Management. Each layer is responsible for providing a specific function. For example, the Physical layer provides connectivity between devices and the Data Link layer is responsible for data transmission. The Transport layer is responsible for routing data and the Network layer is responsible for managing the network. The Application layer is responsible for providing services to the devices on the network and the Management layer is responsible for managing the network. Each layer in the OSI model has a specific purpose and each layer in the OSI model has a specific role to play in the overall system.

25. What is the thread in programming?

The thread is a fundamental concept in programming. It is a way of organizing and managing code so that it can run in parallel. The thread is a way of keeping code running in the background while the main program is running. Threads are used to parallelize tasks and to share resources among multiple threads. When the main program runs, it sends instructions to the thread that is running the task. When the task is done, the thread that was running the task sends instructions to the main program that is waiting for instructions. This process continues until all tasks are done or until one of them crashes or gets interrupted. Threads are a fundamental concept in programming because they allow programs to run in parallel and to share resources. They are also useful for managing memory and CPU usage.

Computer Science Interview Questions for Experienced

1. what is normalization in a database.

Normalization is a process of abstracting and simplifying data. It is a way of making data easier to understand and easier to work with. For example, if you have a data set that contains a lot of numbers, you can normalize it by taking the numbers and breaking them down into smaller pieces, such as by dividing by 10. This makes it easier to work with the data and makes it easier to see trends and patterns. You can also normalize your data by making it more consistent.

2. What is Indexing in DBMS?

Indexing is the process of organizing data in a way that makes it easier to find and access. In a database, the index is a collection of data organized in a way that makes it easy to search and find data. The index consists of a set of key-value pairs that can be used to reference data in the database. The indexing process can involve many different techniques, including the use of indexes, data structures, and algorithms. In a database, the index is a collection of data organized in a way that makes it easy to search and find data.

TCP also provides several other functions, such as error detection and recovery, congestion control, and reliability.

5. Explain DNS?

DNS is the acronym for Domain Name System. It's a way of mapping domain names to IP addresses. The IP address is a number that's assigned to each device that connects to the Internet. When you type in a domain name, your computer sends a request to the DNS server, which looks up the corresponding IP address. The DNS server then returns a response that includes the domain name and an associated IP address. This process is called name resolution. DNS is used by most websites and services that use the Internet. It's also used by email services like Gmail and Yahoo Mail, as well as by many online services like shopping sites and online banking services.

6. What are the Application layer protocols?

The Application layer protocols are the protocols that are used to connect applications to the network. These protocols are responsible for transferring data between applications and the network, such as TCP/IP, HTTP, and FTP. The Application layer protocols are also responsible for handling security and privacy. For example, the HTTP protocol is used to transfer data between web pages and the network. The HTTP protocol is also used to protect privacy by encrypting data before it is sent over the network.

7. What are the keys in DBMS?

8. What is Multithreading?

Multithreading is a technique that allows multiple threads to run in parallel on a single processor. This allows multiple tasks to be run in parallel without the need for synchronization. In addition, multithreading can improve performance by allowing tasks to run in parallel without having to wait for each other to finish. For example, it is not appropriate for applications that require high performance or when the processor cannot support more than one thread at a time. Multithreading also has its own set of risks and pitfalls. For example, multithreading can lead to increased system load and increased system resource consumption.

9. What is a Critical Section?

A critical section is a section of code that is crucial to the operation of a program. By accessing critical sections, a program can make changes to the overall functionality of the program without affecting other sections of code. Critical sections are often accessed through functions, methods, and variables. The purpose of a critical section is to ensure that all parts of the program are working properly.

10. What is Deadlock?

A deadlock is a situation where two or more processes are waiting for each other to finish. Deadlock occurs when one process is waiting for another process to finish before it can continue. The process that is waiting will not finish until the other process finishes. This can be a problem if you need to wait for a long time, as this can lead to your system becoming unresponsive.

11. What is Cache?

A cache is a temporary storage location for frequently accessed data. Caches are useful for organizations that need to store large amounts of data in a short amount of time. They can also be used to improve performance by reducing the amount of data that needs to be retrieved from the network. Caches can be used to store data in several different ways. They can be used to store data that is frequently accessed, such as documents or images. They can also be used to store data that is rarely accessed, such as log files or application states. They can also be used to store data that is needed only occasionally, such as temporary files or cookies.

12. What are multiple inheritances in Java?

Multiple inheritances are a way of passing on multiple copies of a particular class or interface to a child's class. This can be useful when you want to make sure that some code is always available to your child's classes. One way to do this is to create a subclass of the parent class, and then provide the child with a copy of the parent class. Another way is to create multiple inheritances in your Java code, and then provide the child with a reference to the parent class. Multiple inheritances are useful for situations where you need to make sure that some code is always available to your child's classes. In Java, multiple inheritances are implemented using the public and private modifiers on a class or interface. When multiple inheritances are present, the public modifier indicates that the class or interface is publically accessible. The private modifier indicates that the class or interface is privately accessible. Multiple inheritances can be useful when you want to make sure that some code is always available to your child's classes.

13. What is a wrapper class?

A wrapper class is a class that inherits from another class and then provides a set of methods and/or properties that are specific to its own purpose. Wrappers are typically used to hide implementation details from the user, allowing the developer to concentrate on the business logic. A wrapper class can be used to hide implementation details from the user, allowing the developer to concentrate on the business logic. Wrappers can also be used to provide a set of methods and/or properties that are specific to their own purpose. The main advantage of wrappers is that they allow you to hide implementation details from the user, allowing you to concentrate on the business logic. The main disadvantage of wrappers is that they can be difficult to maintain.

14. Is string class final?

Yes. The string class is final. This means that you cannot subclass it, and you cannot override its methods. This is a good thing because it means that you can use the string class without worrying about its internal state. There are a few things that you can do to subclass the string class, though. First, you can use StringBuilder to create a subclass of the string class. This class can then override the methods that you need to override to create your own subclass of the string class. Second, you can use StringBuffer to create a subclass of the string class. This class can then override the methods that you need to override to create your own subclass of the string class. Finally, you can use StringBuilder and StringBuffer together to create a subclass of the string class.

15. What is a singleton class?

A singleton class is a class that is defined once and only once. This can be used to reduce the number of classes you need to define in your application, and it can also be used to reduce the complexity of your code. When you define a singleton class, you are declaring that the class is only ever going to be created once. This can be useful if you want to reduce the number of instances that your class will have to create, and it can also be useful if you want to reduce the complexity of your code. Singleton classes are often used when you need to create a single instance of a class, but you don't want that instance to be shared across multiple objects. For example, if you want to create a single instance of a class that represents an image, you might create a singleton class that represents that image.

16. What is cryptography?

Cryptography is the science and art of creating and using codes and ciphers to protect sensitive information from unauthorized access, disclosure, or destruction. Cryptography is used to protect data from unauthorized access, modification, or disclosure. Cryptography can also be used to secure data transmissions, such as e-mail and web browsing. Cryptography also plays an important role in the security of computer networks, such as the Internet. Codes and ciphers are used to encode and decode information. For example, when you type in a password on a computer, the computer uses a code to encrypt the password. When you send an e-mail, you use a code to encrypt the message.

17. What is an Algorithm?

An algorithm is a set of steps that are used to solve a problem. Algorithms are used in a variety of fields, including computer science, mathematics, and engineering. An algorithm is a set of instructions that tells a computer how to perform a task. Algorithms are used to solve problems such as sorting data, searching for patterns in data, and performing calculations. Algorithms are used in many different fields, including computer science, mathematics, and engineering. An algorithm is a set of instructions that tells a computer how to perform a task.

18. What is the World Wide Web?

The World Wide Web (or WWW) is a collection of interconnected data networks that enable people to share information, documents, and programs across the Internet. The web is made up of hundreds of different websites, each of which contains information about a particular topic or subject. These websites are organized into a hierarchy called a “web page” that describes the content of the page and links to other pages. Web pages can be written in many different languages, and they can be organized in many different ways, including using tabs and links. The web is a powerful tool for sharing information because it enables people to easily access information from anywhere on the planet. For example, you can access information about any topic you want from any computer or device that has Internet access. You can also use the web to share documents and programs with other people who have access to the same devices as you do.

19. What is the internet?

The internet is a worldwide network of computers and devices that enables people to share information, ideas, and products. It is made up of many different types of networks, such as the internet, mobile networks, and satellite networks. The internet is used for a variety of purposes, including communication, learning, and entertainment. The internet was originally created to allow people to share information and ideas.

What are some typical questions one might be asked in a Computer Science PhD Viva?

I know that you are likely to suggest "Ask your supervisor. He/She will know best.".

While that is obviously true, I would like to know from your personal experience either as the PhD candidate or as the examiner: What should I expect in my viva?

For example:

Should I expect to be asked about the history of my topic?

About the research cited in my thesis (i.e references - will they ask me about them? I have over 100...)?

About methods used?

About justifications for my conclusions?

What should one expect, in general, to be asked? I am PhD student in the UK.

There is one critical question that is asked in every Phd viva, be it either directly or indirectly, that is "what is the original contribution of your thesis to knowledge". To be awarded a Phd the result of the research must be to contribute something new to the planetary or disciplines store of knowledge. You must have done something new and know what that thing is.

It is the very purpose of a viva to discover if you know that. Saying "I do not know" to this question can result in a Phd failure.

Other questions will seek to discover if you really understand the works you are citing in your bibliography; have you actually read and understood them and do you know how they relate to your work.

The third aspect of a viva is to resolve any ambiguity that the examiners read into your writing. Which of the possible interpretations of the words and conclusions did you actually mean. You might not have realised that your thesis contained ambiguity but the examiners will certainly find it. They will also seek to expand on or explore elements that are not clearly explained and get you to clarify them.

The answers to all these questions will determine if you have to make corrections to the thesis to resolve these ambiguities or make clarification, or even conduct more research to resolve those matters.

This is written from the perspective of a Phd examiner, both internal and external and experience as an independent chair of such vivas.

I recently (2-3 months ago) passed my PhD viva in Computer Science at a UK institution in the top 100. I will relay the useful points from my viva experience, but I preface this by saying that yours may differ. Ultimately the viva is a product of the examiners, and different examiners have different priorities. To reply to your questions point by point:

I was not asked about the history of the topic at all.
I was not asked to discuss any particular reference in detail.
We did have some very in depth conversation about methods used (specifically my use of Principal Components Analysis), but in a visual sense, not in the sense of having to recall the formulae. This demonstrated that I knew why I was using it, how it applied to my problem and what the novelty of my approach was.
Some of my stated conclusions were not specific enough. This was brought up and narrowing their scope was part of minor corrections.

Whether those are of any use to you is unclear. However, the best pieces of advice I received in hindsight were:

Focus on what you wrote , not excruciating detail on the methods you used and the papers you cited. Read through the thesis in its entirety, and if there is any written or implied detail that you do not feel 100% confident explaining, then go and revise that. My colleagues tell me that their vivas were all focused on the thesis claims and content, and mine was no exception. Don't lose sight of the big picture of the thesis amid the minutiae.
Don't defend the indefensible. If you get caught out on some detail and what you put is wrong, just concede the point, suck it up and move on. It will go into corrections, no big deal. Flogging a dead horse will just make things worse.
As a side to the last point, you should still be robust. The examiners may play devil's advocate, and if they pick up on something that you know is right, this is the time to commit to discussing it. Perhaps concede that it could be explained better in the text if you are struggling to conclude the argument.
Don't burn yourself out. Assuming of course that you wrote the thesis entirely, a week of good revision before the viva should be plenty to get you through.

I hope these are of some help to you.

What should I expect in my viva?

Every viva is unique, but the first question will likely be standard in your department, ask a fellow student (and post the reply in a comment below).

Regarding your specific questions, you may be asked about each of them:

You may be asked to contextualise your research within the broader field.

About the research cited in my thesis?

You may be asked about any citation. For any particularly closely related citation, you may be asked to explain the differences between your work and the cited works.

You may be asked to explain the methods (to demonstrate that you understand them), to justify the appropriateness of the methods, and to explain alternative methods.

I'm not sure I understand the question, could you clarify in a comment below?

30 Computer Scientist Interview Questions and Answers

Common Computer Scientist interview questions, how to answer them, and example answers from a certified career coach.

In the vast and ever-evolving landscape of computer science, those who master the art of problem-solving, algorithm development, data management, and innovative thinking are poised for success. As you prepare for a pivotal interview in your career as a computer scientist, keep in mind that employers will be looking to assess not only your technical skills but also your ability to think critically and stay at the forefront of industry advancements.

To help you navigate this important step in your professional journey, we’ve compiled a list of common interview questions you might encounter when applying for a computer scientist role. Through this article, we aim to equip you with insightful tips and sample answers to confidently articulate your expertise and passion for this dynamic field.

1. Can you describe a complex data structure you’ve created and how it improved a software solution you were developing?

The essence of computer science lies in problem-solving and creating efficient systems. This question aims to assess your ability to design complex data structures, which is a fundamental skill in this field. It also allows interviewers to gauge your problem-solving skills, creativity, and ability to improve software solutions, all of which are critical for success as a computer scientist.

Example: “In one project, I developed a hybrid data structure combining Hashmaps and Linked Lists to create an LRU Cache. The hashmap provided O(1) access time, while the linked list maintained order of usage for eviction policy.

This significantly improved our software’s performance by reducing costly database queries. It stored frequently accessed data in memory, ensuring efficient retrieval and saving computational resources.”

2. Explain how you would handle a situation where your code was not running as expected?

Debugging code is a significant part of a computer scientist’s job. Hiring managers ask this question to gauge your problem-solving skills, and to understand your approach when faced with a challenge. It also helps them determine your ability to troubleshoot, analyze, and find solutions in a systematic and logical manner.

Example: “When my code isn’t running as expected, I first try to understand the problem by checking error messages and debugging. If that doesn’t work, I use print statements or a tool like a debugger to examine the state of my program at various points.

If the issue persists, I would isolate the problematic section and test it separately. This can help identify if the problem is in this specific part or due to interaction with other parts of the code.

In case I’m still unable to resolve the issue, I’d seek assistance from colleagues or online communities. It’s important to be able to ask for help when needed while also learning from the process.”

3. Describe a time when you had to optimize an algorithm for better performance. What was your approach and what was the outcome?

In the fast-paced field of computer science, efficiency is key. Hiring managers want to know that you not only have the skills to write algorithms but also the ability to optimize them. This is because optimization often leads to better performance, faster processing times, and improved user experience – all of which are vital for a company’s success in today’s technology-driven world. Your approach to this situation and the outcome can speak volumes about your problem-solving skills, creativity, and understanding of the intricacies of coding.

Example: “In a past project, I worked on an image processing algorithm that was taking too long to process high-resolution images. My approach involved profiling the code to identify bottlenecks and then applying optimization techniques.

I found that the main issue was repetitive disk operations. To resolve this, I implemented caching mechanisms to store intermediate results in memory instead of constantly reading from the disk.

The outcome was a significant improvement in performance – reducing the processing time by roughly 70%. This allowed us to handle larger datasets more efficiently and improved overall system responsiveness.”

4. How would you explain the concept of object-oriented programming to a non-technical person?

The ability to translate complex, technical information into simpler, understandable language is a valuable skill for a computer scientist. In many organizations, computer scientists often interact with non-technical team members or clients who rely on their expertise. Interviewers want to see if you can break down complex ideas into digestible pieces for those who may not have a technical background. This not only demonstrates your technical knowledge but also your communication skills.

Example: “Object-oriented programming, or OOP, is like organizing a big event. Think of each object as a team member with specific roles and responsibilities. These objects interact to achieve the overall goal, similar to how different departments work together in an event.

In OOP, we have ‘classes’ which are like job descriptions. They define what tasks an object can do. An ‘object’ is an individual who performs those tasks. This structure makes it easier to manage complex programs, just like having clear roles makes managing large events more efficient.”

information systems phd interview from a computer science background

I am applying to computer science PhDs in the US, but since my subfield is pretty interdisciplinary, some of the faculties I'm interested in are in other departments. So I got an interview invitation from an information systems PhD program (the department's full name is Information, Risk & Operations Management and the subfield is Information Systems), but honestly, I have no idea what an information systems interview looks like.

Firstly, in the email they say "We are very interested in talking with you to learn more about you and address any questions you may have for us." This does mean an interview right?

What questions should I expect in an information systems interview? For instance, in CS interviews common questions are: talk about your past projects, your research interests, what are your values in research, long term goals, etc, and maybe some technical questions.

In my application, I mentioned I'm most interested in faculty A and have some interest in faculty B. But only faculty B and another faculty C, who I assume is in charge of admissions, are joining the interview. In this case, is it ok for me to mention my interest in working with A?

Any help is appreciated!
