Technical interviews for BTech Computer Science freshers are often simpler than we imagine—but only if fundamentals are clear.
Based on real interview experiences, here are some commonly asked questions that interviewers use to evaluate fresh graduates.
These questions focus more on clarity, basics, and problem-solving approach rather than deep theoretical knowledge.
1. Tell Me About Yourself / Introduce Yourself
This is usually the first question in any interview.
Interviewers want to understand:
-
Your background
-
Your communication skills
-
How confidently you present yourself
Tip: Keep it structured — education → skills → projects → career interest.
2. What Subjects Have You Studied During Your BTech in Computer Science?
This question checks your academic exposure.
Common subjects interviewers expect:
-
Data Structures & Algorithms
-
Operating Systems
-
DBMS
-
Computer Networks
-
OOPS
-
Software Engineering
They may ask follow-up questions from any subject you mention.
3. Which Subject Is Your Favorite and Why?
This question helps interviewers:
-
Decide the direction of the interview
-
Check your depth of understanding
Choose a subject you are confident in, because cross-questions will follow.
4. What Type of Projects Have You Built During Your BTech? Explain Them One by One.
Projects play a huge role for freshers.
Interviewers want to know:
-
What problem your project solves
-
Your role in the project
-
Technologies used
Even a simple project is fine—as long as you understand it clearly.
5. What Challenges Did You Face While Building Those Projects and How Did You Overcome Them?
This question checks your:
-
Problem-solving skills
-
Learning mindset
-
Practical experience
Interviewers value how you handled problems, not whether your project was perfect.
6. Are You Comfortable With Coding?
This is often a filter question.
If you say yes, be prepared for:
-
Basic coding questions
-
Logic building problems
Be honest. Confidence matters, but overconfidence can backfire.
7. Which Programming Language Is Your Favorite and Why?
This helps interviewers understand:
-
Your coding comfort
-
Your learning journey
Popular answers include Python, Java, or C++, but the key is why you prefer it.
8. Write a Program to Reverse a String Without Using Built-in Functions
A very common basic coding question.
This tests:
-
Logic building
-
Loop understanding
-
String handling
Interviewers usually care more about your approach than syntax perfection.
9. What Is a Deadlock Situation in Operating Systems?
This checks your OS fundamentals.
You may also be asked:
-
Conditions for deadlock
-
Real-life examples
10. Difference Between SQL and NoSQL Databases
A frequently asked DBMS question.
Interviewers expect you to know:
-
Structured vs unstructured data
-
Use cases
-
Examples
11. Are You Aware of GenAI and Agentic AI?
This is a new-age question, especially in recent interviews.
Interviewers want to check:
-
Your awareness of current tech trends
-
Your curiosity beyond the syllabus
Basic understanding is enough—no deep expertise expected from freshers.
12. What Happens When You Type a URL in the Browser and Press Enter?
A classic fundamentals question.
This tests knowledge of:
-
DNS
-
HTTP/HTTPS
-
Client–server communication
Even a high-level explanation is acceptable for freshers.
13. What Is OOPS? Explain One Principle With a Real-Life Example.
Interviewers want:
-
Conceptual clarity
-
Ability to relate theory to real life
Commonly asked principles:
-
Encapsulation
-
Inheritance
-
Polymorphism
-
Abstraction
Final Thoughts
For BTech CS freshers, interviews are not about knowing everything.
They are about:
-
Strong fundamentals
-
Clear communication
-
Honest project explanations
-
Willingness to learn
If you prepare these questions well, you’ll already be ahead of many candidates.
