The interview was very theoretical. You must study a lot prior to the interview.

I was in an Architect role, and the engineer interviewing me had half my experience. It was difficult to convince him that I no longer remembered things that were already documented.

The interviewer didn't have clarity in his questions.

Most importantly, there was no smile on the interviewer's face.

Overall, it felt like a college viva.
