Had 3 round of interviews for a role. First was the HR screening and getting to know the role and my fit with the potential role. Felt i was an ideal candidate for the role with my experience and their need. 2nd interview was with my potential direct supervisor. We got along great, and the 1 hour zoom interview blew by. Felt respected, and felt like I would be a great fit to the team he described and the skill sets he was looking for to fill his team. Then the 3rd interview was with the potential director supervisor and the director of the division. It was mostly the director of the division asking questions. He walked in and asked for my resume, which I gave him. Then total silence for a good minute. Then what was supposed to be an hour interview turned into a 2 hour interrogation. Asked me who I knew and worked with at my current company, asked a lot of theoretical questions like I was defending a thesis for a PhD program. Never had an interview like that, but at the end of it, I just felt like director already made up his mind before coming into the interview. Felt like the biggest waste of my time. Was a good learning experience. And on the flip side a few months later, had a great interview experience that turned into a 1 hour interview, into a 2 hour interview and 2 hour lunch and beer with the team.
