Common Questions You May Be Asked During a Software Developer Interview

Many fresh graduates prepare for technical questions.

What surprised me was that a large portion of software engineering interviews are not purely technical.

Companies often want to understand:

How you think
How you communicate
How you learn
How you work with others
Whether you'll fit into the team

Here are some common questions I've encountered and what interviewers are usually trying to evaluate.

1. Tell Me About Yourself

Almost every interview starts with this.

Examples:

Tell me about yourself.
Give a brief introduction.
Walk me through your background.

The interviewer usually wants a summary of:

Education
Internship experience
Projects
Career goals

A good introduction should take around 1–2 minutes.

2. Why Did You Choose Software Development?

Questions include:

Why IT?
Why software engineering?
What interests you about technology?
Why this role?

Interviewers want to understand your motivation.

They're often checking whether you're genuinely interested in the field or simply applying because the opportunity is available.

3. Questions About Your Projects

Be prepared to explain:

Your portfolio website
Internship projects (usually the first to be discussed)
Personal projects
Hackathon projects

Common follow-up questions:

Did you build it yourself?
What technologies did you use?
What challenges did you face?
What would you improve?

If it's listed on your CV, assume it can become a discussion topic.

4. Questions About Your Internship (If Applicable)

Examples:

What did you learn?
What was your biggest achievement?
What would you improve?
Did you work independently or as part of a team?

Interviewers often care more about your learning process than the project itself.

5. Technical Fundamentals

Depending on the role, you may be asked:

Web Development

What is a REST API?
Explain GET, POST, PUT, DELETE.
What is MVC?
What is client-side validation?
What is server-side validation?

Databases

What is a primary key?
What is a foreign key?
What is a JOIN?
What is normalisation?

Programming

What is a class?
What is an object?
What is encapsulation?
What is the difference between == and ===?

Many companies focus on fundamentals rather than advanced topics.

6. Scenario-Based Questions

These questions test your thinking.

Examples:

How would you migrate data from one database to another?
What would you do if a customer reported a bug?
How would you debug an API failure?
What happens when a customer clicks "Pay"?

The interviewer is often more interested in your approach than the exact answer.

7. Questions About Learning

Common examples:

How do you learn a new technology?
How did you learn a framework you've never used before?
How would you migrate from Technology A to Technology B?

For fresh graduates, learning ability is often more important than existing knowledge.

8. Questions About Communication

These can be surprisingly common.

Examples:

What would your friends say about you?
What are your weaknesses?
What are you trying to improve?
Tell me about a difficult situation.

Interviewers are assessing self-awareness and communication skills.

9. Work–Life Balance Questions

Some companies ask indirectly.

Examples:

What does work–life balance mean to you?
What would you do if your friends kept you out late before work?
How do you prioritise responsibilities?

These questions reveal how you manage commitments and expectations.

10. Career Planning Questions

Examples:

Where do you see yourself in two years?
What role interests you most?
Why aren't you returning to your internship company?
What are your salary expectations?

These questions help companies understand whether your goals align with the position.

11. Questions About How You Work

Many interviewers want to understand your day-to-day development habits.

Examples:

How do you write code?
How do you ensure your code is readable?
What makes code maintainable?
Do you follow any coding standards?
How do you hand over code to another developer?
Do you use Git?
How do you review your own code?
How do you document your work?

Interviewers are often evaluating whether you can work effectively in a team environment and produce code that other developers can understand and maintain.

12. Questions About AI Usage

As AI becomes more common in software development, interviewers are increasingly asking about it.

Examples:

Do you use AI when coding?
What do you think about AI-generated code?
How do you verify AI-generated solutions?
Can AI replace software engineers?
How would AI improve your productivity?

Interviewers are usually looking for balanced answers.

Most companies want developers who can use AI effectively while still understanding the code they deploy.

13. Software Engineering Practices

Some interviews go beyond programming knowledge and focus on engineering practices.

Examples:

What is exception handling?
Why is logging important?
How would you handle errors gracefully?
What's the difference between displaying errors to users and logging them internally?
How would you write testable code?
How would you debug a production issue?
What happens when an application crashes unexpectedly?

These questions assess whether you understand how real-world software systems operate beyond simply writing code.

14. Code Review and Code Quality Questions

Interviewers may challenge your implementation choices rather than asking you to write code from scratch.

Examples:

Is there anything wrong with this code?
How would you improve this function?
Is this code reusable?
What edge cases should be considered?
How would you refactor this solution?
How would you make this code easier to maintain?

The goal is often to evaluate your ability to review, analyse and improve code.

15. Questions About Self-Learning

Fresh graduates frequently encounter questions about independent learning.

Examples:

What technologies did you teach yourself?
How do you learn tools not covered at university?
What's the most difficult thing you've learned independently?
Can you give an example of solving a problem without guidance?
How do you stay up to date with new technologies?

Many employers expect graduates to continue learning after joining the company.

16. Questions About Strengths and Weaknesses

While weaknesses are commonly discussed, strengths are also frequently asked about.

Examples:

What is your biggest strength?
What skill are you most confident in?
What value would you bring to the team?
What do you think you're better at than most graduates?

Interviewers are often looking for self-awareness rather than perfect answers.

17. Questions About Challenges and Stress

Employers often want to understand how you respond under pressure.

Examples:

Tell me about a challenging project.
How do you handle stress?
What do you do when multiple deadlines clash?
What would you do if a project falls behind schedule?
Describe a difficult technical problem you solved.

Interviewers are usually assessing problem-solving, prioritisation and resilience.

18. Questions About Your Daily Habits and Interests

Some questions may seem unrelated to software development.

Examples:

What do you do in your free time?
What are your hobbies?
Do you play sports?
What technologies are you currently exploring?
What technical content do you follow?

These questions help interviewers understand your personality and how you might fit into the team culture.

19. Live Coding and Technical Exercises

Not every interview consists solely of questions.

Many companies include:

Live coding sessions
Debugging exercises
Code reviews
Take-home assignments
Small algorithm challenges

Examples:

Reverse a string.
Find duplicate values in an array.
Debug a broken API endpoint.
Calculate a monthly loan repayment.
Improve an existing function.

Often, interviewers care more about your thought process and communication than whether you immediately arrive at the perfect solution.

Would you rather work on web development, automation, data or AI?

Companies often use these questions to determine where you would fit best within the team.

22. Questions About Technical Decisions

Interviewers may ask you to explain the reasoning behind your projects.

Examples:

Why did you choose this database?
Why did you use PostgreSQL instead of another database?
Why did you choose React?
Why did you choose Python for this project?
What were the inputs and outputs of your system?

These questions evaluate whether you understand the technologies you're using rather than simply following tutorials.

23. Questions About Company Fit

Not every interview focuses entirely on your technical skills.

Examples:

What kind of working environment do you prefer?
Do you prefer structured guidance or independent work?
Are you comfortable with self-learning?
Do you enjoy research and experimentation?
Would you be comfortable working in a small team?

Interviewers are trying to determine whether you'll be successful within the company's culture.

24. Questions About Ambiguity and Independence

This type of question is becoming increasingly common in start-ups and AI-focused companies.

Examples:

What would you do if nobody knew the answer?
How would you approach a completely new technology?
What would you do if there was no documentation?
How would you solve a problem that requires research and experimentation?
How do you handle uncertainty?

Many employers are looking for people who can work independently when requirements are unclear.

Examples:

What would you do if testers found critical bugs in your code?
How would you investigate a production issue?
What would you do if a feature suddenly stopped working?
How would you identify the root cause of a problem?
What steps would you take before asking for help?

The interviewer is often more interested in your investigation process than the final answer.

26. Questions About Working With AI Tools

Modern software development interviews increasingly include discussions about AI-assisted development.

Examples:

How do you use AI in your workflow?
How would you verify AI-generated code?
What makes a good prompt?
How would you use AI to increase productivity?
What are the limitations of AI coding assistants?

Companies want developers who can effectively collaborate with AI tools rather than depend on them blindly.

27. Questions About Team Structure and Collaboration

Interviewers sometimes want to know how you work with others.

Examples:

How do you communicate with teammates?
What would you do if you're blocked on a task?
When would you ask a senior developer for help?
How would you work in a remote team?
How would you collaborate across different departments?

These questions help companies evaluate communication and teamwork skills.

28. Questions About Job Search Motivation

Recruiters and hiring managers often ask about your current job search.

Examples:

How is your job search going?
What are you looking for in your first job?
What kind of company are you hoping to join?
Are you interviewing elsewhere?
What factors are important when choosing an employer?

These questions help employers understand your priorities and expectations.

29. Questions About Availability

These questions are particularly common for students and fresh graduates.

Examples:

When can you start work?
Have you officially graduated yet?
Are there any remaining academic commitments?
Can you start immediately if offered the position?
Are you waiting for your final results?

Companies need to understand your timeline before moving forward.

30. Questions About Company Research

Many interviewers expect candidates to have done basic research about the company.

Examples:

What do you know about our company?
Did you visit our website?
What products do we build?
Why are you interested in joining us?
What caught your attention about our company?

Interviewers use these questions to gauge preparation and genuine interest.

Even spending 10–15 minutes reading the company website before an interview can significantly improve your answers.

The Question You Should Always Ask

At the end of almost every interview:

Do you have any questions for us?

Never answer with:

No questions.

Some useful questions include:

How does onboarding work?
What does success look like in the first six months?
How is mentoring handled?
What technologies does the team use daily?
What are the next stages of the hiring process?

It shows genuine interest and helps you evaluate the company as well.

Final Thoughts

One thing I learned from attending interviews is that software engineering interviews are not only about coding.

Technical knowledge matters.
But so do communication skills, problem-solving ability, adaptability and a willingness to learn.

If you're preparing for your next interview, don't just memorise technical answers.
Practise explaining your experiences, your projects and your thought process clearly.

Those are often the answers interviewers remember most.
