American Express Data Science interview questions

Asked ML questions in detail. Asked to explain difference between Random Forest and Gradient-Boosted Decision Trees. Was also asked some basic python questions. Questions related to previous job was also asked. Grilled on projects mentioned in the resume

interviewed at amex. the interviewers were very mean and condescending. the case study was nothing like what the recruiter described so i studied the wrong thing the entire time. they rescheduled my interview without asking me if the new time works for me.
