Really interesting and challenging interview process. The HR process was quite long. There were 7 stages: 1 - LeetCode medium task 2 - 1 hour call with coding task 3 - 1 hour call with algorithms task 4 - 1 hour call with current architecture and design approaches 5 - 1 hour call with Engineering Manager to check motivation and soft skills 6 - 1 hour call with System Design task 7 - 1 hour call with iOS-specific coding task All stages were interesting, with practical tasks. The interviewers were friendly and did their best to reduce stress and make a relaxed atmosphere.

Remote/Virtual first round over zoom call with one of their engineers that had some knowledge of the tech stack. That being said they only ended up asking me one simple, standard/general DSA question.
