Mid-level interview question
Each step of your agent is 95% reliable. How reliable is a 10-step task?
Model answer
About 60%, if every step must succeed and failures are independent: 0.95¹⁰. At 100 steps, about 0.6%.
The levers: fewer model decisions (fixed code where judgment isn't needed), checks between steps, and limits on how far it runs alone.
