There were six rounds of technical interviews held . First was with the senior dev, second was with the hiring manager , the third was with the team in Romania. After 2 months there was a call with the VP, CTO and Senior Vice President. The result came out to be negative as their requirement changed during the whole interview process.

Interview was pretty straightforward with minimal difficulty level. However, the interviewer was in a hurry to prove his expertise with varied topics. He was with less than 7 years of experience interviewing 12+years candidate. That explains the rush. Organization should invest some time in training their interviewers on conducting interviews.
