Three rounds of interviews. The first was a panel interview with two interviewers. The second was a 1:1 with the hiring manager. The third was a panel interviewer with three interviewers, where I was asked to present a topic of my choice related to the area for which I was interviewing for about 20 minutes. One panelist never came on camera and left after 10 minutes. Another panelist interrupted me 10 minutes into the presentation, saying that she knew the material in the presentation and I did not need to continue. I spent hours getting my presentation ready, the least this crew could do was listen to it.
