American Express Software Engineer interview questions

American Express attends graduation hiring fairs. They interviewed ~60 students on campus, and moved about 10 of ours along for a coding assessment. This happened in the first week of December 2018. The coding assessment was scheduled to occur in early January 2019 because all of their engineers were taking PTO at the end of the year. I am including the assessment in the interview section below. The actual initial interview was very awkward, with most of the engineers being rather new and unsure of how to conduct an interview. The results took ~2.5 weeks to receive feedback. Feedback suggesting to learn more of the languages tested on was unhelpful and showcased a lack of consistency in their entire interview process. There was little in testing language competency, rather a large test in your willingness and/or capability to devote 20, 30, 40+ hours on a project for free when the company has made no investment in you in return. Most candidates who did receive feedback were told the CSS and design was not up to par, so this seems to be what they are looking for most. -1/10, would not recommend.

I had 2 face to face interviews at their office in Victoria. The first was just me and the recruiting manager and he asked me some common java programming questions. A problem solving question involving factorials and general competency questions. This lasted for about an hour The second round consisted of me answering programming questions on a mac with to interviewers. The questions were generally about how to implement a restful web server with CRUD operations.
