I applied online and a recruiter contacted me by email a couple of days later. The interview process was as follows:

1. Introductory video call with the recruiter
2. Automated online assessment (about 10 questions, one of them a simple coding problem, the others general web development questions)
3. Interview with the hiring manager. Mostly non-technical with "tell me about a time you did X" type questions.
4. One hour coding video interview. 40 minutes dedicated to solving a LeetCode type problem (didn't expect this for a principal level position, to be honest) and 20 minutes for me asking questions. This interview was extremely rushed.
5. One hour systems design video interview. They asked me to prepare a 10-minute presentation about a past project in which I had a leadership role, 30 minutes dedicated to a design exercise for which they provided background information in advance, and 20 minutes for free-form Q&A.
6. Offer
