Three rounds, medium leetcode + machine learning research questions. Possible that research questions are vague and the team themselves isn't much knowledgeable about LLMs. The position demands researcher and a software engineer in the same role without letting you do open research once you get the offer.

a little difficult. the interview last 60 mins, will ask the projects and leetcode, need to anser in 25mins [dynamic programming, array, linked list, and also ask the time complexity and space complexity.]
