Two rounds. First round was 30 minutes, talking about standard stuff like job experience, skills, projects, etc. Almost two months later I had a second round which was 2.5-3 hours long. 3 coding questions, which weren't too hard although the first one I struggled on. They didn't expect the code to compile, psuedocode was fine. Then I spoke with 2 higher-up managers who asked more questions on skills/experience/etc but also had a mini quiz on C++.

Had pretty standard online first round. A mix of technical questions and some behavioral ones, but mostly technical. A few weeks later, they had an in-person interview. This was mostly simple algorithmic computer science questions, such as finding and removing duplicates in a list, and efficiently traversing a tree of numbers. I spoke with three different people, and that whole interview was at least an hour long. I think the interview went well. But then, they never followed up. I sent at least one follow-up email, but they never responded. I get it if I was not a good fit for the role, that's fine. But ghosting me after bringing me in-person interview did not sit right with me.
