Had a recruiter screen then interviews with hiring manager and rest of team, followed by a case study and one more final interview. The process took about a month. The recruiter was very bad at following up and I ultimately got ghosted. If they are going to make you do a case study, they should at least have the decency to send a rejection. The case study was very labor intensive.

Met with 5 or 6 managers, one after another. Most seemed very invested in the process. Asked focused and relevant questions. HR had provided me with a schedule, and we adhered to it pretty well throughout the day. Had lunch out, and that was an interview, too. So essentially there was no break in the day. But that was fine with me; the process made good use of the full day.
