1. Phone screen with a recruiter, 2. "tell me about yourself" style interview with a couple of engineers 3. Technical interview where I was asked to walk through two situations, one was a code review, one was a system design (simple SSO system). 4. Technical Exercise The big one at Auth0 is the technical exercise. They say it takes between 10-15 hours, but that's only if you want to deliver absolute minimum requirements and have your boilerplates ready to go - it took me more like 20+ hours and, to be frank, was just way too long. They open up a slack channel for the duration (about a week), provide you with some system requirements and you have to design and build a full stack application according to a spec. The spec has some vague parts in it, specifically so you have to communicate with the team in the slack channel and try and lean on them as resources - interaction is as much a part of the interview as the thing you're building. You have to demo your MVP at the end of about a week to the team - describe your process, describe what your next steps would be, what you had trouble doing, what you couldn't do, etc etc.
