Unfortunately no "write me multi-head self attention by hand" :(, so not good enough for 2024's DL interviews.
Honestly it will be a miracle if an indie game dev like me gets the job of a machine learning research scientist. Can't say they asked the wrong questions.
FWIW some types of game devs are actually versatile people for ML engineering. They can write low level code; they can manipulate bitmaps; they have keen-enough eyes to tell you something is wrong with your image dataset. I don't think game devs are a bad choice.
