I was applying through the referral. There was promised 4-5 stages with 3 technical. Unfortunatelly, after the 3rd tech interview I was withdrawn from the process with the standard answer "we have more technically skilled candidates". No other details were provided and no feedback even after I explicitly asked the recruiter. Overall, the process was not bad, and I still glad I got the chance to join the team. BTW, all the tasks were finished and worked, but my solution for the last one was not so optimal, and I didn't come up with the corner case, but I was able to handle it after I got a clue.

Long process with 2-3 week gaps in between the interviews. It took about 8-9 weeks in total to go through 3 coding sessions. Coding tasks are easy to light medium (1 case) leetcode level. The biggest challenge was that 2 out of 3 interviewers were not fully competent in tech areas they were discussing. And they would not accept any reasoning and act in a "boss culture" mode instead, going as far as putting pure lies in their interview notes. Default way of communication from HR was to just keep silence. After some extensive pushing I've got a GPT generated response. And after another round of pushing I was able to get a short summary of interview notes. Company is apparently aiming for faang style tech interviews, but fails miserably on implementation. Interviewers are going for cargo cult ego boost sessions with almost nothing in the process being related to a real technical expertise. The outcome of such a process is purely random of course. Enormous waste of time.
