They sent a take-home exercise before anything else. It was a HackerRank series of 4 questions to be completed in 1 hour. It seemed as if one of the problems was set up incorrectly and the test cases would not run. And then the recruiter said I did not pass because on that question I didn't anticipate one of the test scenarios. Very frustrating.

There were a lot of rounds but I the interviewers made it a good experience. Spoke with a recruiter over the phone, followed by a HackerRank assessment, then 4 back-to-back style interviews on Zoom with 2 hiring managers and 2 engineers. Process in total took about 3 weeks from application to offer.
