My interviewer was very nice and seemed like a chill guy. He asked me to talk about what I did in the past and to name a cool coding project that I did in the past for fun. He asked me how to traverse a binary tree in order. I first solved it recursively, and then he asked for the iterative solution (no parent pointers allowed).

2 Rounds of standard leetcode questions and one behavioral round. Typical Meta questions were used and the last round had 2 coding questions followed by some behavioral and standard interview question time.
