I went for the interview from college placement process for the quality analyst position .There were 4 rounds - 1) Online apti+technical test 2)Group Discussion after that we were asked for the interview in the company but when I reach there I had to give one more written technical test .After clearing all rounds I was asked for the technical interview in which the Interviewer asked questions about software engineering , testing, Sql queries . Everything was going smoothly but at the end after clearing all rounds they didn't select me saying your are good just need to enhance more which was not reasonable as I think .
