This was in late 2020 (all virtual) for their growing cloud division in Seattle, WA.

The first interview was a single technical interview. I had a video call with an engineer and completed a question with code sharing.

The final round virtual onsite consisted of 5 interviews: 4 technical ones with engineers and 1 behavioral one with the engineering manager.

Although I am rating the process as difficult, I think the questions were reasonable and similar to what you'd find in LeetCode medium level. A few were straightforward, and a few were more challenging but doable with enough practice or hints from the interviewer.

Focus on trees, data structures, etc.

One of the questions was coding-based but design in nature, i.e., building a class. I did not get a strictly design question.

Most of the engineers I interviewed with previously worked at Microsoft and Amazon, so expect questions that those companies would normally give.
