There was a phone screening with the recruiter, who was incredibly nice and friendly. He was very easy to connect with and from that call quickly moved me to speaking with the engineering manager. The engineering manager was not as friendly, very rude and didn't seem prepared to give an interview. He didn't seem to have a clear idea of what the project was and seemed to be asking questions on the fly.

Smooth. First coding screen, then a phone screen, then a virtual onsite consisting of 4 different interviewers. The first one was a fit/culture interview, then 3 coding interviews. A lot of class design, and some leetcode. Done on a platform WITH A COMPILER.
