Payments PM interview guides

Payments PM interviews reward domain depth. Interviewers ask about auth rates, interchange, disputes, ledger design, and settlement. They test the compliance layer too: KYC, AML, and PCI DSS.

This hub holds every payments guide in the library. Start with the complete question set. Then work into the areas your loop will test. Company guides cover Stripe, Square, PayPal, and Marqeta.

A working payments product leader wrote these. The same material runs in my 1:1 coaching sessions.
