Due to the COVID-19 situation, the company conducted online interviews via Skype. In my interview session, the interviewers were very nice and amicable. I talked about myself, my prior experiences, and what I am going to provide this organization to achieve its vision if I get selected. As I talked about my lines of works which are pretty similar to the positions I was interviewing, they seemed very interested in me. I was asked two to three situational/behavioral questions. Overall the interview session was very good; I didn't even expect an online interview can be that good.
