At least 1 phone interview about past experience and some coding interview questions. One or two site interviews with about 4 engineers for technical questions and one bar raiser. The bar raiser is an experienced one but sometime they are not from the same field that you are applying for. Questions can be anything. There are some interview guidelines, but most of the time engineers do not learn the guidelines. The second onsite interview most of the time is to see the managers and directors level, but sometime also has some technical questions.

Internal recruiter reached out to me over LinkedIn. Had exploratory calls with 3 teams, because my background was wide enough to be a potential fit for all of them. Had a first-round phone-screen. Worked on a fairly-easy leetcode-style problem. Admittedly, the implementation wasn't production-quality, given that we only had like 20 minutes to write code. So I decided to re-work the problem the next morning, and made a perfectly working implementation. Still got the corporate brush-off note a few days later. That folks, is what I call BS. Stay away from these guys. They only want perfect code on the first go. If only they practiced that in their everyday coding, their products would be much better.
