I applied through college or university. The process took 3 weeks. I interviewed at American Express in Oct 2014
Interview
Met with AMEX at a college career fair and had a great first impression. Everyone seemed really passionate and enthusiastic about the company. The process took about 2 weeks to get an interview from the career fair. People kept telling me that I would not need any technical skills for the job or interview and that they would teach me on the job.
The interview was suicide for a person who hasn't taken high level math and Java courses. Asked me to write code, solve math problems, and problem solve for various situations. There were behavioral questions, but mostly technical. Interviewers were very friendly and encouraging and I heard back from the interview 9 days later.

I applied online. The process took 2 months. I interviewed at American Express (New York, NY)
Interview
The questions asked in the technical tests were very algorithm-focused and also covered a lot of tricky corners cases in the syntactical details of the Java programming language. I was surprised the interview process took so long - it was just over 2 months from start to finish before I finally got an offer. In between I had 5 phone interviews, 6 on-site technical interviews, a drug test, a full background screening from an independent company and a personality test conducted by 4 of the senior project managers. Towards the end I was getting tired of the process and was tempted to let go of the position but the position was very convenient for me because it was such a short commute - unfortunately I ended up moving later because of external circumstances, but that's beside the point - it was a really long process - they certainly left no stone unturned.

Interview
Met at career fair, had interview two 45 minute interviews on campus. Next round was on-site the following week, two interviews. The format of all the interviews were the same - a mix of behavioral/situational questions followed by some technical questions, most of which did not require writing code down. Interviewers were very friendly and supportive.
