I applied online, passed an initial coding test using coderpad, spent about 8 hours total on a homework assignment, then spent a day consisting of another coding interview, a design interview, some odd HR culture/behavioral test, and a final interview with a department head.
I had several telephone calls with the recruiter, which she often forgot, or didn't really give me any worthwhile information.
I made a couple of mistakes in hindsight, mentioning the CAP theorem during the design interview but saying CAS (I guess I was working too much on lightweight transactions at the time) and spending too much time wrangling my test cases in coderpad and not being able to distinguish properly compilation errors from assertion errors.
I never got any feedback for the final interviews from the recruiter, detailing any of my shortcomings and ways to improve, and the feedback on my homework was positive but vague stating that the results were incorrect without any concrete counterexamples, all said over the phone of course.
Overall I got the impression that they are too enamored with their speculative market capitalization and sometimes downright pretentious on many levels. I did enjoy the HR interview though, we spent about an hour talking about web crawlers and ways to beat cloudflare and circumvent bot detection, and the interviewer seemed more down to earth, with some of the same aspirations as myself, wanting to do more remote work and enjoy a better quality of life.
