American Express Software Engineer interview questions

One phone call, then a live coding assessment. The phone call was talking about my experience, and the live coding assessment was working with an API making some UnitTest methods work. You were given the choice of language.

I was referred. There was a single interview lasting an hour and a half. They began with behavioral questions and a resume review. They then asked me about Java fundamentals as well as some questions related to OS. They then gave me a coding problem (LC easy) and wanted me to talk them through it. FInally I had the opportunity to ask questions to the two interviewers.
