Overview
Affirm interviews are the most accessible in fintech. With 55% medium and 35% easy, the coding bar is friendly. Affirm focuses on buy-now-pay-later infrastructure, so system design questions involve credit decisioning, payment scheduling, and risk assessment. The process is professional but not intense. Affirm values pragmatic engineering — solutions that work reliably over theoretically optimal algorithms.
