After completing the online application and relevent online testing, there is a phone interview which lasts approximately 20-30 minutes. The questions are straight forward competency questions asking about motivation, why AmEx, why Finance etc.
if successful, you'll be invited to an Assessment Centre which consists of an individual presentation on a selected case study, which you have 1 hour to extrapolate information and present it; 2 face-to-face interviews and a group exercise.
On the whole, the day was very enjoyable, you meet alot of new people and have the change to talk to current interns/employees of American Express
