It was 4 levels. First a phone interview where a few maths and machine learning questions were asked. Then a take home project to use machine learning models to predict loan approval. Then another interview to discuss my findings on the machine learning project. Finally another interview where machine learning questions were asked

One round of video interview with both behavioral and easy technical questions. Then got invited to fly to Charlotte for a 2-day superday interview and a visit to their headquarters. Overall, a very pleasant journey and not hard interviews compared to other banks.
