- I was asked questions on each CS subject including Networking, DBMS, OOPs, and OS.
- The interviewer (Engineer Manager) was in love with OOPs and we had an hour-long discussion about various concepts it got a bit frustrating for me by the end (NGL).
Verdict: Not cleared.
TIPS:
- Revise CS fundamentals.
- Be ready for philosophical questions on these concepts too.
- Be patient and you don’t need any high level of DSA concepts for this.
