I had a Zoom interview with the hiring manager which lasted 45 minutes. The interviewer had a fairly serious demeanor and it felt very professional but transactional. It lasted 45 minutes and there was nothing I recall that was much beyond boiler plate. To use a dating metaphor, we didn't have any chemistry.
Several coding assessments and some non-technical as well. Overall a good process. Thorough. Got to know people and understand the company better. Final stage took about half a day. This information may be out of date.

Interview
HR interview - general questions to determine if you fit in with the company culture. 2 questions, 15 mins each - Each question had a different interviewer and you were allowed to use the internet to help solve the problem, in their words "[they] want to test your ability to program, not your ability to remember random algorithms".
