After initial phone screens with two recruiters, I was scheduled for an "on-site" interview. However, this was during COVID, so the interview was actually remote.

Interviews were back-to-back with short breaks in between, and a lunch break was included between one of them.

The process was tough, but fair.

Each interview asked me to either design a large-scale system via diagrams and describing its large parts. One interview required me to pseudo-code an algorithm.
