I had 3 rounds of interview. 3rd round of the interview was the reason one of the interviewer did not show up on 2nd round. After I finish the interview I have waited for couple days and then I emailed to the recruiter about the decision. He said he is not one to contact about the process. This part was funny because he is the only one I could contact. Endless rounds of interviews, interview questions are very specific and interviewers are not qualified.
