First you take a Google cultural fit online assessment, then 3 rounds of interviews (2-5 interviews each round), and one take home assignment that is supposed to take around 4 hours to complete.
I applied through an employee referral. The process took 2 months. I interviewed at Google (Zúrich) in Oct 2025
Interview
Intense but professional. You need to do a lot of prep but thankfully that's widely available online. All the rounds were described by the recruiter and when I wanted more clarity on what one would cover I was provided the opportunity to ask more questions.
There was a phone screen with a recruiter and then three interviews over Google Video Chat. Everyone was very professional and friendly. They did their best to put you at ease. They used automated notes taking during the interview process.
