Autoscaler lag under spike
An autoscaler scaled the fleet down during a lull, then traffic spiked and it couldn't add capacity fast enough (slow instance startup), causing an overload. How do you respond and prevent it?
What a strong answer looks like
Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
Run or narrate your approach, then ask the coach.
