Phone screen, then virtual onsite. Onsite has 4 rounds 2 coding 1 system design, 1 behavioral. For one of the coding rounds it was not a typical coding question. Gave immediate optimized solution but interviewer seemed unhappy with the approach, and wanted to start from a simpler slower solution. This didn't really make sense to me and at this point my interviewer and I diverged and were not on the same page anymore. The product seems useful. For coding, I would say start really slow, and only code what the interviewer is expecting as the answer, as anything else is a fail.
