I went through two rounds of technical interview. The First round was with the team lead . He asked basic questions on AI/ML . Mostly the questions were based on the projects that were done by me. The second round was much more tough as there were two interviewers. They also started with questions based on my project and then started to ask each and every algorithm in ML . The questions were tough and they try to confuse you so be prepared for it. Clear your basic concepts and you should be good to go
