American Express Software Engineer interview questions

I can't disclose the questions since I signed a contract but they will focus in your communication skills and confidence of your answer more than the technical aspect so prepare to be questioned about anything you answer, if you say this algorithm is better you need to support the reason with a lot of confidence, don't hesitate and don't use words like "I think", "perhaps", etc. It took them 3 weeks just to reply to the online application and another 2 weeks to schedule the phone interview

I had an interview during a conference in October. I was given 2 hours notice from handing my resume over to having a 2:1 interview. I interviewed with a software engineer and an HR rep. The interview consisted of behavioral and technical questions and had a laid-back feel. The technical questions revolved around basic data structures and algorithms similar to what you would see in a Data Structures or Design and Analysis of Algorithms class. I also had to write a simple MySQL query on a given relation. Additionally, I looked at simple classes in Java and located/described bugs. I talked myself through each step out loud and asked questions as I had them. I was given scratch paper, which they kept for analysis. I wrote down as much as I could and did my best to explain all of my decisions. I also showcased my other talents outside of programming to show myself as a well-rounded candidate.
