There were four interviews:

1. Screening with a recruiter about general topics, including introduction, motivation, role, and tips.
2. Technical coding (1 hour and 15 minutes) covering two algorithms – an easy and a hard version of the same algorithm, plus general questions about web architecture.
3. Technical coding (1 hour and 30 minutes) again focusing on general web architecture questions and a medium algorithm.
4. System design (1 hour and 30 minutes) about designing three endpoints to be queried with ranges on bare machines.

All interviews were friendly and professional. The last interview, about system design, was with someone who was practicing their interview skills. I answered all the questions, and they ran out of topics 30 minutes before the scheduled end time. I was confident that I passed it; however, it turned out they gave bad feedback, and I was rejected.
