First round was great, talked with the actual manager who I'd be working with and he took an extra 20 minutes to talk, he was really nice and seemed to see my potential for growth as well as what I'd bring to the team.
Second round was with a director who seemed like they were only going to follow a script and ask the same questions. I understand keeping things standardized across interviews but it felt like I was just data to be collected, not a person to be understood. They weren't mean about it or anything, very polite and professional, but not as engaged as my first round.
Turns out in that interview I think we both realized I was looking for something different, so it didn't matter that much in the end.
