It was nearly a month-long interview process, and they were quick to schedule the next interview. I had five interviews total with the recruiter, hiring manager, and various collaborating team members—a very enthusiastic bunch! The recruiter notified me that I didn't get it about a week after my last interview.

Don't bother applying. They'll put you through at least 4 rounds of interviews and then ghost you. Very unprofessional. It's fine to choose another candidate but they should at least let you know.
