Pinterest Machine Learning Engineer interview questions

Initial Leetcode round with a few ML related questions about LLMs, then onsite was 2 more leetcode rounds and 2 systems design interviews. This was genuinely one of the worst interview experiences I've ever had. The interviewers feel like they would rather be anywhere but there. Many of them were incredibly rushed and one had an office room rented that he was getting kicked out of so he just hung up the call without any time for questions or even a good bye. The worst part was one of the interviewers was actively trying to trick me. I said the right answer and then she would say "are you sure", I would reiterate yes and then she would say "are you reallyyy sure" until i second guessed myself and changed my answer since if someone says that, it must be wrong, but then she would be like ha wrong! Stay as far away as possible, they put the least amount of effort into the interview process of any company I've ever interviewed with, the questions are lazy and there's no training for the interviewers, clearly.

Recruiter reached out via linkedIn for recommendations role. Got asked a LC medium and then a medium/hard continuation involving recursion. Got rejected as I couldn't come up with an answer for the continuation. Decent interviewer, poor hints.
