I applied online. The process took 1 week. I interviewed at American Express (Singapore) in Mar 2012
Interview
Online Applicaton, an assessment centre containing critical and numerical tests as well as a group activity and presentation, all followed by networking. If you get through the interview, there is an interview with two business managers.
It was 2 rounds, behavioral mostly... very friendly interviewers, and I heard back within 10 days. Overall, they ask common behavioral questions that you should prepare for. My interviews were virtual, not sure if it is any different now
