Recruiter screen, interview with someone on your team that you'd work with, and then case interview with two senior-ish level employees.
Case study was interesting, thought I did well. Some of their behavioral questions were really odd though. Basically asking "how have you delt with [oddly specific situation] in the workplace. Ultimately they were basic behavioral questions, but they added an additional specification for seemingly no reason.
Pannel interviewers were curt with little-to-no back and forth. Just asking more questions the moment I wrap up the answer. Upon reflecting, it seems like they didn't want to interview me, and I was a 3rd or 4th choice from the start.
