I applied through a recruiter. The process took 4 weeks. I interviewed at American Express in July 2008
Interview
First I had an interview with a person from HR. She liked my background and asked about my different jobs I have had. She talked abut the company and the position in detail.
The second interview was with two managers. They asked me to describe my experience in chronological order. They asked me questions about my projects. Asked to give an example of a disagreement with my boss and how I handled it. Asked about managerial skills.
I applied online. I interviewed at American Express
Interview
3 rounds, HR screening, managers interview, director interview,
mostly on your experience and your competency.
Some questions were repetitive. Took a few weeks in total. HR quite responsive. But feel like the whole process can be a bit faster.
I applied through an employee referral. I interviewed at American Express
