I was contacted by a recruiter on LinkedIn.

After that, I had one 45-minute phone/HackerRank coding interview.

Then, I had an on-site that consisted of three whiteboard coding interviews (one with two people). The questions were on the difficult side, but they were fair and mostly standard.

After my last interview, I ate lunch with a Forward Deployed Software Engineer and talked about the company.

It was a very pleasant process, aside from the A/C being broken in their building (they provided a fan in the interview room, which helped a lot). Everyone I interacted with was very nice.

My recruiter was probably the best one I've ever worked with. She was great about setting everything up and telling me what to expect. She even had the courtesy to give me the rejection over the phone (the only recruiter I've ever dealt with to do so).
