Initial round was a 45 min tech screen which had a easy level leetcode problem along with a nested query SQL problem and some basic ML fundamentals. Second interview was a 1hr tech screen - ML questions related to past work & projects, deep dive into basic concept. However, the second interview person was very unprofessional - was laughing for no reason when I was explaning, for one of the questions said that the answer was wrong ( it wasn't ) when asked why, did they couldn't give an explanation / edge case that would fail with the given answer. Basic communication skills of interviewers are very sub-par. Toxic inter-personal skills and culture - stay away.
