Recently, I received my offer letter from TCS for the System Engineer Trainee role. 🎉
I wanted to share my interview experience because it might help someone preparing for their interview.
Questions I was asked:
- Tell me about yourself
- Four pillars of OOPs
- Java vs C++
- What is JIT? — I couldn’t answer this 😅
- SQL query for maximum salary
- Basic DSA question on strings
- Deep Learning layers
- Difference between AI, ML & DL
I was nervous before the interview, but once it started, I stayed confident. The preparation I had done really helped me.
My biggest takeaway:
-
Focus on your resume.
-
Know everything you mention on your resume.
-
Revise your fundamentals.
-
Practice basic DSA & SQL.
-
Be confident, even if you don't know every answer.
-
Don't just answer questions — have a conversation with the interviewer.
You don't need to know everything. Good preparation + confidence + communication can take you a long way.
Hope this helps someone preparing for their next interview.
