Walk me through an incident you personally caused. Focus on what you communicated, to whom, and when.
What they are really testing: They already believe you can debug. They want to know if you can run the human side of an incident, because bad communication turns a 20 minute outage into a lost customer.
A real interview question
Walk me through an incident you personally caused. Focus on what you communicated, to whom, and when.
What most people say
drag me
“I found the bug quickly and fixed it, then I told everyone once it was already resolved so nobody had to panic about it.”
Sitting on an active incident to avoid alarming people is the exact behaviour that erodes trust, and it leaves support answering angry customers with no information.
The follow-ups they ask next
Why hand comms to someone else instead of doing both?
Say it simply, the person fixing cannot also be the person typing updates. Naming an incident commander and a comms owner is standard, not a sign you cannot cope.
What if your manager told you to wait before telling support?
Do not fight in the moment, ask what threshold would make it reportable, then raise the general rule in the postmortem where it is a policy question, not a personal one.
How do you decide when a blip becomes a declared incident?
Give a pre-agreed threshold, for example error rate above one percent for more than five minutes, so the decision is made before the adrenaline, not during it.
What the interviewer is listening for
- Named themselves as the cause in the channel unprompted
- Separated the fixing role from the comms role
- Briefed support before customers complained
- Improved the comms path, not only the code
What sinks the answer
- Delayed telling anyone until the fix was done
- No sense of update cadence during an incident
- Treats support and customer teams as an afterthought
- Only technical learnings, nothing about coordination
If you genuinely do not know
Say this instead of freezing. Reasoning out loud from what you do know beats silence every single time, and a good interviewer is listening for exactly that.
“I have not run a customer facing incident yet, so let me tell you how I would sequence it. Declare early, say out loud that my change is the suspect, hand comms to someone else, roll back, and brief support before the tickets arrive. Here is the closest thing I have done.”
