American Express Developer interview questions

Amex had an info session at my college campus where they told us everything about Amex, right from their work culture to the kind of challenges they face in serving a huge customer base. I had a coding challenge which involved solving 2 questions in 20 minutes. I was able to solve 1 question completely while the 2nd one was halfway there. The questions were not very tough due to the short time period. I had a second round wherein I interviewed with the Tech Delivery Lead. It was a 45 minute technical interview. I was asked to explain my academic projects and work experience in detail.

Applied through campus career fair. Was given on campus interviews. Two 30-minute sessions with different interviewers. Then interviewed on sight in Phoenix. Again two 30-minute sessions with different interviewers. Both rounds ask behavioral and technical questions. The second interviewer for the on campus interview asked one problem solving question to I think try and understand your thought process in approaching a problem. Interviewers read from a sheet of questions given to them
