Responsive recruiters, good accommodations, and lots of transparency. You get a tour of the building, learn about company culture, eat with current TDPs, and then do three different interviews.

Initially was sent an online assessment. Several months later I was asked to interview. The 4 hour interview consisted of 3 different parts. The technical question was extremely easy. The behavioral aspect of the interview was 3 straight forward STAR questions. The last part was a technical case which was also really easy. They began by asking me a bit about a new hypothetical feature. They then asked me to review some code. This last part I think was the trickiest but really not too bad. For context I've completed 150 leetcode questions. The interview questions weren't really leetcode style but it definitely helped to be good at writing/reading my language of choice.
