I applied through an employee referral. I interviewed at Google (Zürich) in Nov 2019
Interview
There was several rounds of interviews, each consisting of 1-3 medium leetcode problems. After you pass them all, you have a host matching process, where you are 1to1 with your possible manager, describing their project and understanding if you are a perfect fit with them. At the end you select which you like.
