Interview Preparation Tips
I dint feel comfortable right from the start of the interview. The interviewer was condescending and not accepting even correct answers and claiming I failed to know basic stuff required for the role. I ended the interview in less than half the time it was scheduled for. I'm sure I don't want to work under such a person who wants to keep rejecting answers and pointing how you did not know answer to a question.
Interview is generally to understand how good the candidate is and how good the company is. After first 5 mins of the call I knew I dint want to work there. He added a team member just to tell him if there was any important thing he had to look into (like that other guy is some kind of service assistant to him).
Even after I accepted I wasn't the right fit for the role and bailed, he again pointed out how I barely knew anything that I should for the role (which is not necessary as the interview is over).
I applied via campus placement at Nitte Meenakshi Institute of Technology, Bangalore and was interviewed in Nov 2024. There were 4 interview rounds.
