Explain the incident without assigning unsupported blame
For an incident postmortem interview, distinguish customer impact, observed events, contributing conditions and proposed actions. State what the evidence supports. A useful review explains how the system and process allowed the failure, rather than ending with a named person to blame.
This original exercise is for SRE and platform applicants to international teams in Europe. It complements incident-response questions by focusing on the review after recovery. The case is fictional and does not describe an outage at Cluegent or another company.
Review an outage after a configuration change
In the practice case, a configuration change causes requests to fail for one service. Monitoring detects errors, but the alert reaches a team that no longer owns the service. Recovery happens after the current owner is contacted and restores the previous configuration. The brief does not provide a reliable affected-user count.
Write a short review that identifies the change, the delayed routing and the successful recovery. Separate confirmed facts from hypotheses. Ask how the configuration was checked and how ownership records became outdated. Do not invent financial loss or a precise root cause.
| Section | Evidence to include |
|---|---|
| Impact | Known failed requests and uncertainty about affected users. |
| Timeline | Change, detection, misrouted alert, owner contact and recovery. |
| Contributing conditions | Validation and ownership questions that require investigation. |
| Actions | A named owner, a deliverable and evidence of completion. |
| Unknowns | Information needed before finalising the explanation. |
Write actions that can be verified
A worked action is: 'The service owner will update the alert route and run a controlled notification test to confirm it reaches the current on-call team.' It has an owner and a observable result. 'Improve communication' does not specify what will change.
A second action could investigate a pre-release configuration check. Explain what failure it should catch and where it will run. If the check cannot prevent every outage, state its scope. Avoid a large action list that nobody can prioritise or verify.
Follow-up questions to test your reasoning
- Which statement is a hypothesis rather than a fact?
- How would you verify the alert-routing action?
- What evidence would change the proposed prevention action?
Check that the review distinguishes mitigation from prevention. Restoring the previous configuration recovered service; it did not by itself correct the conditions that allowed the change and delayed response. Keep the language factual and explain uncertainty.
Present the review to a non-specialist
Explain the incident to a partner without using team-specific shorthand. Ask them to repeat the impact, recovery and next action. If they can only recall a person's name, revise the explanation so the system conditions and proposed changes are clearer.
This is an original Cluegent practice exercise. Its scenario, example wording and suggested timings are illustrative, not an employer's assessment or scoring system. Use genuine experience in a real interview.
For optional preparation, paste the exercise into Cluegent as a typed prompt and ask for one follow-up at a time. Review the reasoning before adopting suggested wording. Redact personal and employer-confidential information. Try Cluegent on Windows or macOS; check the current trial and paid terms before downloading. Follow the employer's rules during an actual assessment.
