"name": "What is the Affirm software engineer interview process like?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Affirm's interview process typically includes a recruiter screen, a technical phone screen (45 min coding), and an onsite loop with 4-5 rounds: 2 coding rounds, 1 system design round, 1 behavioral/values round, and sometimes a domain-specific round for fintech knowledge. The coding rounds are LeetCode medium difficulty. Affirm values clear problem-solving communication — explaining your thought process out loud scores better than a silent correct solution."

"@type": "Question",
"name": "What technical areas does Affirm focus on for engineering interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Affirm focuses heavily on backend systems and fintech-relevant topics. Expect coding problems around arrays, graphs, and string manipulation. System design rounds often involve payment processing systems, financial ledgers, fraud detection pipelines, and high-availability transaction systems. Knowledge of ACID properties, distributed transactions, idempotency, and event sourcing is particularly relevant given Affirm's BNPL (Buy Now Pay Later) infrastructure. Affirm uses Python and Go heavily — demonstrating proficiency in either strengthens your candidacy."

"@type": "Question",
"name": "How does Affirm evaluate culture fit in interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Affirm looks for alignment with their mission of 'honest financial products' and their values around transparency and consumer advocacy. Behavioral rounds probe for examples of ethical decision-making, especially in situations where short-term business gain conflicted with customer interests. Candidates who can articulate the social impact of fintech — responsible lending, financial inclusion — resonate well. Affirm also looks for collaboration signals: how candidates handled disagreements with product or design teams on feature decisions."

"@type": "Question",
"name": "What salary range can I expect for a software engineer role at Affirm?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Affirm total compensation for software engineers varies by level. SDE I (new grad) typically ranges from $150,000-$185,000 total comp including equity. SDE II (mid-level) ranges from $200,000-$270,000. Senior SDE ranges from $270,000-$380,000. Affirm equity is in RSUs that vest over 4 years. As a public company (AFRM), the equity value fluctuates with the stock price — candidates should factor in vesting cliff risk when evaluating offers. San Francisco and New York roles are comp-equivalent; remote roles may be slightly lower."
