IBM Data Science interview questions

technical screening was sent immediately after application. Reasonable challenge with ample time for position being considered. The interview consisted of one question using jupyter notebooks using machine learning to solve a company question

It is a very long process and you are contacted by a different person almost every time for scheduling interviews. It was a 2 and a half month process for me which included 1 assessment, 1 automated video interview, 1 HR interview and 1 interview with a data scientist. After investing so much time I only got a generic rejection email. Tried contacting the last recruiter that talked to me and got no reply. Overall, the interview were not difficult.
