The experience on this page is for an American Express Technology Engineer Trainee campus role in 2025. It describes an online assessment, technical round, and managerial round. It is a useful fresher account, not a template for experienced engineering interviews.
\nThe candidate reported three OA coding questions, but did not publish their statements, so they are not counted below. The technical round included Climbing Stairs and Maximum Subarray Sum, followed by fundamentals questions. The ten prompts below are the named questions from that round:
\nThese prompts come from the American Express Engineer Trainee interview experience on GeeksforGeeks (2025). The technical-round list stops at ten named questions, even though the source contains additional topics.
\nThe candidate also described questions about serverless computing, prompt engineering, and SQL queries to find the second-highest salary and employees ranked tenth through fifteenth by salary. The report says the candidate did not receive an offer. These questions are in the same Amex account (2025).
\nThe technical round connects algorithms to fundamentals and resume projects. When practicing database questions, use a concrete example and explain the trade-off, especially under concurrent writes. For SQL ranking, decide how ties should behave before writing the query. These are preparation suggestions based on the prompts, not additional questions reported by the candidate.

\nA second LeetCode Discuss post is titled as an American Express online assessment with three coding questions. The captured question notes mention a set of coordinate points, a rectangle perimeter P, greedy reasoning, and clean C++ implementation, but do not preserve complete problem statements. I am keeping those details as assessment themes rather than inventing three questions. (LeetCode AMEX OA report)
No. The candidate reported three coding questions but did not publish their statements. The named coding and computer-science prompts on this page came from the later technical round; the managerial questions are listed separately in the 2025 report.
