Affirm Software Engineer interview experience

Posted Sep 2025 · Candidate report, summarized by Dataford

My SWE II process started with a concrete technical screen that felt very “real code adjacent.” I was given a mostly implemented but broken class that parsed JSON-like records with fields like loan id, ticket id, and status, and the job was to decide whether something looked fraudulent.

I had to fill in missing methods and correct the logic, including issues around sorting.

The screen lasted about an hour, and I liked that it wasn’t just a clean, whiteboard-style algorithm problem. The interviewer’s setup basically forced me to debug and complete existing code in a systematic way, which set the tone for the rest of the process. In the end, I didn’t move forward, but the format itself felt aligned with how engineering work actually looks—read, reason, fix, and get to correct behavior.
