Was invited to a fast track hiring event by an internal recruiter. After a brief conversation I was given a HackerRank coding test to complete. The solution had to include space and time complexity comments and I think you were given 60 minutes once the question was revealed. Got notified that I passed and was given a date for the on-site interviews. Instead of the process being drawn out over several days/weeks, all interviews were on one long afternoon. Four candidates got briefed together by the recruiter and then we all went off to a series of four interviews. Some interviewers had a second person there for training purposes. From start to finish this was the smoothest and most organized process I'd ever participated in.
