Started with some coding exercises, then a behavioral interview. The stage I was rejected at was the following panel interview with live coding, as interviewers were very hostile and laughed while I was coding. After an email withdrawing my application, I got a personal call from the Lead Hiring Manager explaining the two people that interviewed me were very new to the company - one there for <5 months and an intern.

Smooth and quick. first round was a discussion with team lead. technical questions regarding optimization, c++, etc. second was with 2 members of the team, general CS/CE very similar to previous and final 2 were: 1 coding round, medium level leetcode and 1 with board member non technical mostly motivation/fit etc.
