Went through the full amex PM interview loop about 6 weeks ago for a senior product manager role on the consumer card side. Sharing questions and observations because I couldn't find much PM-specific content when I was prepping.
First thing to know: amex PM interviews are heavier on behavioral than product case. This is not a McKinsey-style case interview and it's not a Google-style product design deep-dive. It's more structured and competency-based.
Recruiter Screen: Same as what others have described. Comp, background, why amex. 30 minutes, nothing technical.
Technical Screen (yes, even PMs): A 30-minute call with a tech lead. They asked how I've worked with engineering teams, how I handle technical decisions as a PM, and one light "explain a complex technical concept to a non-technical stakeholder" question. No whiteboarding or SQL. Just checking that you're not going to be helpless in an engineering meeting.
Onsite (virtual, four rounds):
Product design: "How would you improve the Amex app experience for cardholders who travel internationally?" Full 45 minutes. They wanted user definition, problem space, prioritized features, and success metrics. They pushed back on my initial user segmentation, which was useful.
Analytical: "You launch a new travel reward feature and DAU goes up but spend per user goes down over 90 days. Walk me through how you diagnose this." No SQL, but they wanted a structured analytical framework. Metrics, hypotheses, tests.
Strategy: "How would you think about expanding Amex's presence with younger cardholders?" Broad, ambiguous, market-sizing adjacent. They were more interested in how I structured my thinking than the specific answer.
Behavioral: Classic STAR questions. Cross-functional conflict, stakeholder management, a product bet that didn't work.
Tip: Amex is a brand company as much as a fintech. References to customer trust, premium experience, and brand cohesion landed well. Generic fintech speak ("move fast") felt slightly off-key in the room.
