First, you will likely have one interview with the HR department. They will check your status and get to know you overall. Then, based on which team you're applying for, you'll be interviewed in 1-2 rounds. The depth of technical discussions in interview will be variable based on your team and the interviewers, but generally, I found the interviews more technical in comparison with other company interviews. This might be because positions typically have a slightly research-based nature. Great company, friendly people, professional and technical interviews.
