I applied through college or university. I interviewed at American Express (Mumbai) in Aug 2016
Interview
Amex came to our campus for its summer internship recruitment and interview was kinda chill without any HR round. The profile was Risk & Information Management but question that were asked comprised to general analytical skills and no deep profile specific knowledge, though they asked why amex. They mostly looked for my reasoning ability in the entire process however some prior knowledge of credit cards can be beneficial if you are appearing in an interview.

They asked questions based on real life problem of authenticity of credit cards faced by both offline and online businesses and how to tackle them.My other co interns were asked few famous interview puzzles.
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.
