The Interview Process:
I submitted my application on November 20th and received a shortlisting email for the interview scheduled on December 13th. The entire process was virtual and conducted via Zoom. The HR representative called out names for short introductions, and candidates were then taken to a lobby where they awaited their turn. Patience is key as the waiting time can vary.
I was interviewed in the 1st-2nd turn. The interviewer emphasized honesty—if unsure, it was better to say “pass” than to provide incorrect answers. Here are the questions I faced during the interview:
