    After a brief phone interview I was called onsite. I was spoke to the entire team and they were very nice, down to earth people. I answered most of the answers pretty well and I was almost certain that I cracked the interview. But unfortunately, I wasn't offered the job. When I asked for additional feedback, I was told that the team felt I was more inclined towards development rather than testing which was true. But nevertheless, it was a great experience.
