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 when I was interviewing for graphics driver roles I didn't use to ask this, nor was I asked it when I was interviewed myself, but this might be very different to what gets asked of rendering engine folks
