American Express Java Engineer interview questions

Started with a HackerRank Java exercise with some multiple choice questions. Then did a general phone screening interview, and the last stage was a technical interview at the office with two employees.

I had an initial facetime interview during which I was asked basics about Java and edited a shared document a couple times to show basic Java skills. This was followed by a facetime interview with two engineers and a project manager where I was asked more about the intricacies of Java and talked about projects, experience, etc.
