Eight questions worth preparing
Public practice prompts, not leaked questions from any employer. Pick one for a 10-minute drill with follow-ups and a report.
- 01As a Site Reliability Engineer, walk me through a real project that shows your SLOs. What did you personally own?Drill
- 02Tell me about a time incident response competed with a hard deadline. What did you prioritise and what did you give up?Drill
- 03Describe a time your work on observability fell short. How did you find the cause and what changed afterwards?Drill
- 04How would you explain a incident response decision to a colleague outside your field, and what if they disagreed?Drill
- 05You inherit a project with problems in SLOs. What evidence do you gather and what do you do in the first two weeks?Drill
- 06Which achievement on your resume best shows you are ready for a Site Reliability Engineer role? Separate your part from the team's.Drill
- 07Before answering a case question about observability, what would you clarify with the interviewer and why?Drill
- 08Tell me about a mistake you made in SLOs. What do you do differently now?Drill
In-depth role guide
Scenarios and answer checkpoints
Interviewers prioritize candidates who treat incidents as systems problems and maintain SLOs through rigorous observability.
Scenario 1
A critical service is consistently hovering near its error budget threshold due to minor latency spikes. How do you triage this without triggering burnout for the on-call engineer?
A strong answer will
- Analyze latency telemetry to isolate the root cause.
- Quantify the risk of budget exhaustion against current performance.
- Propose automated remediation to offload manual toil.
Scenario 2
During a production outage, you have limited diagnostic time. How do you utilize observability tools to identify the failure point while coordinating with the engineering team?
A strong answer will
- Establish a clear incident command structure immediately.
- Use metrics and traces to isolate the component failure.
- Document actions taken to ensure post-mortem accuracy.
Common mistake: Avoid focusing only on 'fixing' the bug; emphasize how you improve systemic resilience and preventative monitoring.

Question 1 of 3
As a Site Reliability Engineer, walk me through a real project that shows your SLOs. What did you personally own?
Fundamentals the interviewer probes
- CI/CD pipeline design and rollback strategy
- Infrastructure as code and environment parity
- Observability: metrics, logs, traces, alert quality
- Incident response, postmortems, SLOs and error budgets
- Containers and orchestration (Docker, Kubernetes) trade-offs
- Cost and security hygiene in cloud accounts
Follow-ups to expect
- “Describe your worst production incident: timeline, what you did, what changed afterwards.”
- “How do you decide what deserves an alert at 3am?”
- “Walk me through your deploy pipeline and where it can fail.”
