Interview

Interview questions

Short questions on how failures grow, such as feedback loops and retry amplification, metastable failure, cascades, gray failure, contention, death spirals and overload defences, each with an answer you could give aloud and a link to the full explanation.

Scenarios

Longer problems on how failures grow and how to stop them, of the kind asked in senior interviews: each one estimated with numbers, diagnosed, and answered with its trade-offs.
