Two related questions for computer graphics people:

1. is it true that ray/line/whatever intersection tests are common in interviews?

2. how common are questions of this nature, where you have equations memorized?🤔

(boosts appreciated pls)

@ruba it depends on the studio I think. Mine doesn't, but studios with a more dated hiring philosophy might try to grill you on stuff like that. In my experience, the content of a job description is usually a pretty good hint for what they're going to ask you about in an interview and what you should review beforehand.
@aeva @ruba I suspect it'll depend on the studio, yes. We don't ask that kind of questions, at least
