On-Call Rotation
Also written as On-Call, PagerDuty
A schedule where engineers take turns being responsible for responding to production alerts and incidents outside of normal working hours.
Think of it like
Like a building's after-hours emergency maintenance line — someone is always designated to pick up if a pipe bursts at 2am.
Junior or senior?
Junior sounds like
Endures a high-noise on-call rotation without questioning it.
Senior sounds like
Can describe what a typical week looked like — how many pages, how many were real — and whether the team worked to reduce them.
Ask them
“What did a typical on-call week look like for you — how many pages, and how often were they real issues versus noise?”
