QA teams have tiers, like to test whenever game is good for public, if it's fun. And then those technical fields and I actually studied pretty hard for that. iwas doing menus which were scrapped and I was offered position of someone who is sitting just below technical engineres and try to break things or fin broken things and then I had to in technical terms said them what happened. Because you have that overlay with profiler, etc. However it was insufficient the size of the team and budget so that's why the release was like it was. Also the Cry engine is tough one. Kingdom Come Deliverance if interested. Was fun tho. And certainly I refrain for many of the edgy takes about technological side of things without knowing how it was conducted, because sometimes you get absolutely insane bugs. Which is very hard to solve, so if you do not know the answer and some person above you does not have the time, you go to code...etc.
