Applied in July, got phone interview in August, on-site in September.

The phone interview was conducted by a recruiter. Most of it was behavioral, but they asked technical questions that they clearly weren't qualified to evaluate.

Examples included questions like "What data structures and algorithms were used in that project?" when 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, there were four straight coding interviews. It wasn't terrible, but it was pretty difficult. A couple of the interviewers felt somewhat aggressive, questioning my choice of answering in Python (which I've never had a company care about) or straight-up ignoring some things I said.

I received a call about 1.5 weeks later that I got the offer.

Trees, greedy algorithms, sorting
