Many rounds of data structure and algorithm questions, then a behavioral interview. The algorithm questions are LeetCode-style, and you are expected to explain your solutions and ask questions.

There are two rounds of phone interviews, followed by an onsite interview. The entire process took about four weeks. The questions are based on real-life examples. It was not very difficult, but they expect perfect code.

The interview process was incredibly laborious and lengthy indeed. This was for the role of Software Engineer at Google, located in the Bay Area (not in San Francisco proper).
