My Amex GCS interview was underwhelming. The technical interviewer barely introduced himself, seemed distracted, and cut me off while I explained my project. He dismissed ML altogether and rushed me into basic questions. In the HR round, one person yawned mid-answer, and when I asked about the role, they vaguely said, “You’ll figure it out.” Overall, it felt like they weren’t interested in the conversation or the candidate.

Question 1
What’s the time complexity of accessing an element in a list
I interviewed at American Express (London, England)
Interview
Online coding challenge, followed by an in person day in Brighton focusing on a team coding challenge. Great fun, loads of friendly interviewers and freedom to express your ideas. This way they can cover your coding skills, teamwork and usual behavioural questions.
I applied through college or university. The process took 2 weeks. I interviewed at American Express (Hong Kong) in Mar 2026
Interview
Video Interview, very smooth but the preparation time is very short. Some questions are hard to answer but the limited time force me to answer quickly. There is only one chance for the interview. It can not be stop during the interview period.
Group interview with 5 other people, 30 min for excel in the end. Interview process was very smooth and easy, interviewers were nice. the group interview is the only real selection step after video interview
