American Express interview questions

Applied online which included a personality and skills test that took about an hour to complete. About a week later received a call to set up a phone interview, after that a one on one interview with the hiring person. She asked about my past experiences (why I left, why am I the best for the job, why AMEX type of questions), toughest question was, "you have an irate customer and you cannot transfer to a supervisor or another rep, what do you do?", I answered I would hear the customer out so that they can let their frustration out then explain why the situation occurred and offer a solution, always staying calm and professional and moving the call forward so we don't dwell on the problem but the solution.
