Three phone screens, one face-to-face interview. The phone interviews were reasonably high level with a recruiter following a script. The face-to-face involved a series of technical challenges or discussions. The challenges ranged from specific (e.g., write some code to achieve <x>) to generic (how would you approach <y>) and always involved a lengthy discussion.

HR round after applying, then coding screening round, if passes, then final round which consists of four coding round or three coding and one design round. Problem difficulty medium to hard.
