I had worked for Google as a third-party contractor for over a year before my interviews.

So, I didn't have to participate in any phone screens.

There were four technical interviews and a lunch "interview" onsite in Zurich, Switzerland.

After the interviews, the process of gathering recruiter feedback, various hiring committees, and team matching, among other things, took over a month before I finally got the offer.

It took another two weeks after getting the offer to finally receive a contract to sign. So, patience is recommended.

I had four onsite technical interviews. They covered a few basic algorithms, such as:

• Union-Find
• Graph search
• Topological sorting

They also explored ways to scale these algorithms. The questions were fairly creative and open-ended.
