Hackerrank involving debugging a web app. Then a brief, low stress phone call with a recruiter. If you do well, they invite you onsite and they put you up in a super swanky hotel. Office is super cool. Onsite interview involves debugging a flask app and adding enhancements, followed by a talk with a manager. Relatively low stress, the interview was very unusual for a tech company, but IMO a realistic assessment of daily work. My first tech interviewer didn't really provide any help, my second was better about that. Not necessarily difficult, just unusual (but I think in a fair way). Company culture seems mixed, my second interviewer seemed kind of unhappy with the company. Thought that was strange. But everybody was very pleasant and communication was fast. Overall, a good experience.
