Affirm is a fintech company building buy-now-pay-later infrastructure and lending products. The interview process typically runs 4-6 weeks and involves a recruiter screen, a technical phone screen, and a virtual onsite with 4-5 rounds.
For engineers, expect one round focused on data structures and algorithms (Leetcode medium difficulty is the baseline), one system design round that skews heavily toward distributed systems and payment reliability, and at least one behavioral round. Affirm's engineering culture has historically valued people who can reason about financial correctness: edge cases in payment flows, idempotency, and failure modes come up often in system design. Be ready to talk about tradeoffs at scale.
For PM and business roles, the loop emphasizes product sense (they will give you a product scenario tied to lending or checkout UX) plus cross-functional collaboration stories. Affirm operates in a regulated space, so questions about working with compliance or legal are common.
Affirm tends to move faster than larger FAANG-adjacent companies on decisions once the onsite is done, though recruiter communication quality varies by team. Compensation is competitive for fintech and includes RSUs.
