3 Rounds of interview : first with recruiter, then hiring manager and then technical expert. I was supposed to present in the last one , but the technical expert had some glitch about the interview and then after one hour called in my phone (instead of video). I had to email my ppt to them. From the very beginning, they gave me impression that I was overqualified (they seemed not to care about my technical PhD and said I have very long experience), so I got discouraged that they continued interviewing me for 3 rounds.
