Generally a positive experience. Everyone involved in the interviews were really friendly and I could see that AmEx were not all talk when it came to company culture. Each interview stage was quite concise yet I was able to talk a lot which is something I really liked. I felt that I was being heard by everybody interviewing me. The questions they asked were easy to answer. From the second stage interview it did take AmEx 2 weeks to get back to me regarding their decision which was nail-biting as it was longer than I was expecting however when I received the rejection, they provided me with feedback which was positive (they just chose a candidate which more experience handling complex and larger organisations).
