I applied through other source. The process took 1 day. I interviewed at Flex (Chennai) in Feb 2020
Interview
It was a walk-in interview. The workplace was so cool. The first round was F2F interview. I was asked about my experience and two questions were asked from core Java and SQL. I failed to answer the question. But the interview was good enough to give a positive experience.
