Turn fraud data into shipped decisioning strategy across Product, Engineering, Ops, and Finance
This interview tests SQL/Python fluency applied to real fraud and identity-verification decisioning, plus the ability to work full-stack across Product, Engineering, Operations, and Finance to ship and measure a fraud strategy change. Expect questions on building tiered cutoff frameworks for ML fraud models, running online experiments, and communicating loss/conversion tradeoffs to both technical and non-technical audiences.

- Online experimentation to test new fraud features
- Communicating fraud/loss tradeoffs to technical and non-technical audiences
Common question themes
Walk through a SQL/Python analysis that changed a fraud or conversion decisioning strategy
How would you set tiered cutoffs for a fraud ML model, and how do you reason about the fraud-vs-conversion tradeoff?
Describe working with Engineering to launch an online experiment testing a new fraud feature
How do you explain a portfolio loss or fraud-rate trend to Finance stakeholders who aren't technical?
Tell me about evaluating a new or unconventional data source for fraud risk signal
