I had two phases of interviews, one was with the manager and it was 15 mins, the other one was a technical interview which was 45 minutes. I liked the experience.
One hour programming and algorithms problems that can be found on leetcode or hackerrank and one hour machine learning theoretical discussions and implementation of some neural network and training process on dummy data, using internet resources but with shared screen.
Interview questions [1]
Question 1
A modified bfs problem
Theoretical concepts about ml but also about programming.
