I applied through an employee referral. I interviewed at Google in Dec 2019
Interview
No coding interview. Two rounds research interviews back to back, 45 mins each. They go into details of projects you did before. I interviewed in December and heard back about 1-2 months later. The recruiters are nice and interviewers are friendly.
A online applications then technical interview where a recruiter and team member led me through some problems. I chose Python but you can choose another language if you wish or are more comfortable with another one
