Initial Recruiter screening - as per the industry standards Phone screen - Easy LC (Real fun begins..) 7 round of onsite interviews. Most of the senior interviewers were great. One of the technical interviewer carried a big ego in the interview and was the worst amongst all the interviewers. Finally, he ended up having a big say in the panel and cited un-obvious reasons to fail me. One final observation, for principal engineer level - they had software engineers interviewing the candidate - I wish I flagged this initially and didn't attend the interview but recommend others to not make this mistake. You get interviewed by people either at or above the level you are interviewing for..
