Screening - recruiters prep material was on qkv attention, which I studied and learned how to do in pytorch from scratch. I could probably do it straight from memory at this point. Then the interviewer only asked about attention free transformers. What was the point of giving me prep instructions that would never be used? I don't feel I was able to display any kind of ML knowledge or any other kind of skillset during this interview. All this showed me was they're looking to over index on someone who can quickly figure out matrix manipulations and not much else. My interviewer also had no ML background from what I could see on his LinkedIn.
