What I Wish I Knew before Going On-call

Abstract: 

Being a software engineer means owning a production system—you have many users and your company's revenue relying on your products. Firefighting a broken system is a time-sensitive and stressful part of life as an engineer. New engineers entering an on-call rotation may be overwhelmed by this responsibility. How should we act in an emergency? How can we make a system emergency-friendly? In this workshop, we will share how new and future on-call engineers can be successful by guiding participants through exercises to triage real-life engineering emergency scenarios. We will also cover how on-call engineers can share learnings within an organization to prevent future fires.
