Applied in July, got phone interview in August, On-site in September
The phone interview was done by a recruiter. Most of it was behavioral, but they asked technical questions that they clearly weren't qualified to evaluate. Asking things like "what data structures and algorithms were used in that project?" where it clearly didn't make sense, or "how many lines of code was that project," which is a pretty bad sign
In the on-site, it was 4 straight coding interviews. Not terrible, was pretty difficult. A couple of the interviewers felt somewhat aggressive. Doing things like questioning my choice of answering in Python (which I've never had a company care about) or straight-up ignoring some things I said
Received a call about 1.5 weeks later that I got the offer
