Does Affirm ask system design questions for software engineers?
For most mid and senior software engineer roles, Affirm includes at least one system design round alongside coding and behavioural interviews. Junior and new-grad loops lean more heavily on data structures, algorithms, and a behavioural round.
How should I prepare for the Affirm software engineer behavioural round?
Prepare 5–7 STAR stories covering ownership, conflict, failure, and cross-team work, each with a clear personal contribution and a measurable outcome. Practising them on camera with a timer is the fastest way to tighten delivery.
What languages should I use in a Affirm coding interview?
Use the language you are most fluent in — usually Python, Java, Go, or C++. Interviewers assess problem-solving and communication, not language trivia, so pick the one that lets you write clean, correct code quickly.
