Multiple calls with different recruiters in with different specialties, my process was handed off between 5 different recruiters before an onsite. When I arrived the final recruiter did not show up, was greeted half an hour late by a temporary employee who grunted hi, showed me to a room, and sat playing games on their phone. 5 in-person interviews had a mix of expected and interesting questions, evaluation appeared to be focused on how well prepared you were for each question.

Very self-driven, first of multiple rounds, where I had to take the initiative to arrive at the problem, constraints, approach, solutions, tradeoffs and reasoning behind it in a matter of 30 minutes.
