I wonder if he had to answer a few Leetcode / Codility problems first.

The warm up rounds to filter out the fluffy includes asking what is a Matrix, do this calculation, what is a LLM. 2nd round include stuff like explain the binary search algorithm, write a double linked list in C, and a take home project.

Would have been great to hear that his inability to do the interview memorization bullshit as a senior was why he didn't get hired somewhere like OpenAI. lol.

Except the good companies probably dont make you do silly stupid outdated interview practices without the tools you can actually use on the job today, right?
