American Express Software Engineer interview questions

Very straightforward, interviewed in person the day after talking to them at the job fair. Talked to 2 interviewers, one behavior and one technical. Very smooth process, and the interviewers were nice and understanding.

I applied online, and was sent a codility interview that had 6 questions on it, about 1.5 hours to complete. After this, I was invited to the next round of interview which consisted of 2 interviews back to back, one behavioral, one technical
