American Express Software Engineer(Internship) interview questions

Interviewed with two different software engineers. After having some difficulties with one of the interview questions the interviewer was clearly uninterested in anything else I had to say. The second interviewer even walked out in the middle of me solving a problem.

The day involved a CV based interview with individuals from the technology team, and a group technical challenge which involved an opportunity for me to showcase my technical skills in a team exercise. All information regarding these exercises was provided on the day so I don’t need to prepare anything in advance, other than researching American Express, understanding my motivation to want to work in Technology, and ensuring I have reviewed your CV.
