Coinbase Sr. Data Scientist interview questions

There were 6 interviews and a cognitive assessment, spaced out over 3 months - a recruiter screen, tech screen, communication and organisation, live coding interview, team fit, then a presentation on a take home assignment that takes a few days to put together. Was ghosted by the recruiter after the final round, any attempts to get information on the interview was met with claims that they were still making decisions. Incredibly unprofessional on their part, would not recommend this interview process to anyone.
