My worst Interview experience in last 12 years. 12 different persons interviewed in month long long recruitment process. 4 technical rounds and rest are consulting/behavior related. Initially I was very much interested in the role but my interest went down gradually after 5th or 6th round. Last interview was phone interview. Senior manager from US called 30 min late on Friday evening around 21:30. All AT&T, BT problems are attributes as mine!. Repeated same set of question 5th time and that was the last straw I could take in!.
