    Interview

    Multiple rounds of brainteasers, probability questions, and game theory/strategy questions. All the interviewers were super friendly. First I was emailed by the recruiter, pretty quickly after applying, and then pretty quickly scheduled a first round. My entire process took about 6 weeks, and I got cut on the third round.
