Interview process

The coding round was the most tricky one, you don't know what problem you will get for the leetcode round.

ML fundamentals, ML design is easy if you prepare for regular ML system designs.

AI coding, do not use the cutting edge models, it takes forever to run. Make sure to downgrade your model, so it answers fast.

Behavioral is pretty standard.

Tips from the candidate

Linkedin is pretty prepareable in terms of the interview, just follow the resources found online. They are more focused on the traditional ML fundamentals than LLMs or transformers. Most of the problems are quite boring.

Company culture

Nothing much, regular big tech style interview. Usually the interviewers are nice.
