1 architecture interview in one day and then another day of 4 coding challenges + 1 Chat session with one of the engineers. Each coding challenge is a one hour session however you get around 30-40 minutes of actual coding depending on how much you talk during the intro

First I was reached through Piazza, which I didn't know happened. Had two video technical calls, they were both pretty on the easy to medium difficulty side, the first one was more of a "brute force write this" "okay now write it with this condition" and all the way to "write it in one line". Pretty fun interview. Second one was with a more awkward engineer, but the problem was quite difficult. Can't remember what it was though sorry.
