I will say it was super quick, I took a super simple OA, then the recruiter contacted me on a Friday to set up a call with some lvl 2 engineer the following Monday. It was 30 mins asking me basic OOP then moved onto final "panel" that same Friday. It was 3 hours long with 4 engineers, 3 engineers didn't say a word the entire meeting. 1 guy led the process and basically just asked me to diagram simple inheritance, and some dependency injection, building on top of each sub problem. They seem super unprepared and I am so confused as to why there were engineers there who clearly had no idea what was going on.
