Google DeepMind interview questions

Got through 3 rounds of interviews without referral. Clear but lengthy process. All people involved were nice and helpful during the process. We reached the conclusion that I wasn't the right fit for the role, the advertise job description was not accurate, they were looking for a software tester instead

I had a screening call with recruiter, followed by an interview with the hiring manager from the team the role was in, followed by two technical interview calls with other research engineers on common python and system design problems (rejected after these)
