American Express Data Scientist interview questions

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.

The interview process began with a phone interview with HR, followed by a round of behavioral and technical questions, then a three-panel interview with technical discussions, a case study, and puzzles.
