You're responsible for onboarding a new junior SRE. Outline a 30-60-90 day onboarding plan that balances technical ramp-up (on-call, monitoring, infra), soft skills (incident communications, blameless culture), and mentoring checkpoints. Be specific about milestones, shadowing activities, and success criteria.

Sample Answer

30 days — Foundation & observation- Goals: access, understand services, tooling, and basic runbook tasks.- Activities: - Complete onboarding (accounts, VPN, pager, CI/CD) day 1–3. - Read architecture docs, SLOs, runbooks for 2 primary services. - Shadow on-call buddy for 2 weeks (observe triage, runbook steps, paging etiquette). - Hands-on: follow a read-only playbook (investigate alerts, reproduce in dev) and complete 3 small tasks (log queries, dashboard edits). - Soft skills: attend 1 incident war room as observer; review incident communication templates.- Milestones / success criteria: can explain service topology, run basic monitoring queries, and execute a read-only postmortem checklist.

60 days — Active contribution & owned tasks- Goals: start handling low-risk incidents, automation basics, and communication practice.- Activities: - Take reduced-scope on-call shifts with a mentor shadow on standby. - Implement a small automation (alert throttling, runbook improvement, or dashboard) and land it via PR. - Lead an incident conference call for a non-critical alert with mentor feedback. - Participate in one blameless post-incident review; draft the timeline. - Mentoring checkpoint: weekly 1:1s to review progress, blockers, and career goals.- Milestones / success criteria: independently resolve tier-1 incidents, merged automation PR, conducts clear incident updates.

90 days — Ownership & improvements- Goals: full on-call rotation, ownership of a reliability improvement, mentor newer hires.- Activities: - Full on-call shifts solo with mentor available asynchronously. - Own a reliability project (e.g., reduce alert noise by X%, improve runbook coverage to 100% for a service). - Lead a postmortem and present a remediation plan to the team. - Soft skills: coach peers in incident comms; run a blameless retrospective facilitation. - Mentoring checkpoint: 30/60/90 review with actionable growth plan and KPI metrics.- Milestones / success criteria: successful solo on-call, measurable improvement delivered, positive peer feedback on communication and troubleshooting, clear roadmap for next-quarter growth.

Ongoing: document learnings, maintain checklist for future onboardees, and schedule quarterly competency reviews.

An application lacks meaningful SLOs. As an early leader, design a workshop plan to help product and dev teams define SLOs and an error budget. Include exercises, sample SLOs (latency, availability), how to coach junior SREs to facilitate the session, and next steps after definition.

Sample Answer

Goals / constraints:- Align product and engineering on reliability targets that map to user-visible outcomes.- Produce draft SLOs + error budget policy in a 3-hour workshop with cross-functional stakeholders.- Leave with ownership, monitoring queries, and next steps.

Workshop agenda (3 hours):1. Kickoff (15m) — Purpose, definitions: SLI, SLO, error budget, incidents vs. bugs.2. User journey mapping (30m) — Break into product+dev pairs; list top 5 user flows and their key SLIs (e.g., checkout success, API response).3. Quantify impact & tolerance (30m) — For each flow, estimate business impact per minute/hour of degradation and acceptable monthly/weekly downtime.4. Draft SLOs (45m) — Convert SLIs into numeric SLOs (latency percentiles, availability) and compute error budget. Use template.5. Error budget policy & playbooks (20m) — Define actions at thresholds (e.g., >50% budget spent → freeze new features).6. Wrap-up (20m) — Owners, monitoring tasks, follow-ups.

Exercises & templates:- SLI brainstorm: availability (successful HTTP 2xx), latency (p50/p90/p99), correctness (data integrity), throughput.- SLO examples: - API availability: 99.95% success rate per month (error budget = ~21.6 mins/month). - Payment latency: p95 < 300ms over 30 days. - Page load: p90 < 1.2s for logged-in users.- Error budget calculation: show conversion from % to minutes and example burn-rate.

Coaching junior SRE facilitators:- Prep: give them facilitation script, SLO templates, sample Prometheus queries.- During workshop: coach to ask “Which user is impacted?” and “What business outcome changes?” Keep conversations concrete and timebox exercises.- Post-workshop: pair them with a senior to convert drafts into dashboard panels, alerts, and automated reports.

Next steps after definition:- Implement SLIs in monitoring (owner assigned), create dashboards and alerting tuned to error-budget burn-rate.- Publish error-budget policy and runbook for throttling releases.- Run monthly SLO review — correlate incidents, feature launches, and budget burn; iterate SLO targets.- Teach a follow-up 1-hour session for engineers to instrument code and validate SLIs.

Success metrics:- SLOs with assigned owners and working dashboards within 2 weeks.- First monthly review completed and one policy-triggered action documented within 2 months.

You discover systemic reliability gaps across many services (flaky alerts, missing observability, no SLOs). As a leader, outline a prioritized reliability roadmap that includes small projects, mentorship of junior engineers to lead initiatives, timelines, risk/impact assessment, and metrics to track progress over the next year.

Sample Answer

Situation: I joined a platform where alerts were noisy, observability gaps existed, and services had no SLOs—incidents were frequent and firefighting dominated.

Roadmap (12 months) — priorities, owners, timeline, risk/impact1. Stabilize alerting (0–2 months) — small project- Actions: Triage top 20 noisy alerts, silence duplicates, add runbooks.- Owner: Senior SRE + paired junior.- Impact: High (reduces alert fatigue). Risk: low.- Metrics: Mean alerts/day, MTTR, alert-to-incident ratio.

2. Implement baseline observability (1–4 months) — small+medium- Actions: Ensure structured logs, basic traces, key metrics per service (requests, errors, latency).- Owner: Rotating junior lead mentored by observability engineer.- Impact: High. Risk: medium (instrumentation effort).- Metrics: % services with tracing/logs/metrics, query coverage.

3. Define SLOs & error budgets (3–6 months)- Actions: Workshop with product/eng to set SLOs for top 30 services; publish dashboards.- Owner: SRE lead + service owners (juniors lead specific services).- Impact: Very high (aligns priorities). Risk: political; mitigate with data.- Metrics: % services with SLOs, error budget burn rate.

4. Automated remediation & runbooks (5–9 months)- Actions: Implement playbooks, auto-rollbacks for common failures, escalate flows.- Owner: Automation SRE + junior scripting owners.- Impact: Medium-high. Risk: automation correctness — start gated.

5. Reliability culture & mentoring (ongoing)- Actions: Pair-programing, 1:1 mentorship, "reliability champions" rotation for juniors to lead a service reliability sprint quarterly.- Owner: SRE manager.- Metrics: Number of juniors leading initiatives, postmortem quality scores.

6. Measure & optimize (6–12 months)- Actions: Quarterly review of SLOs, refine alerts, capacity planning.- Metrics: Availability vs SLO, MTTR, incidents/month, deploy rollback rate, developer satisfaction.

Risk/Impact assessment: Prioritize work that reduces toil and enables visibility first (alerts, observability), then governance (SLOs), then automation. Low-effort/high-impact items first to build momentum and measurable wins.

Mentorship plan: Assign each junior a micro-project (one service), pair with senior, set milestones, review code/runbooks, and present outcomes in a quarterly reliability review.

Expected outcomes in 12 months: >80% services with basic observability and SLOs, 40–60% reduction in noisy alerts, MTTR down by 30–50%, and a sustainable pipeline of junior engineers capable of owning reliability work.

You notice repeated manual firefighting for the same incident. Design a small automation project you would lead to remediate it. Outline milestones, technical options (ad-hoc script, operator, runbook automation), how to mentor junior contributors, testing strategy, and success metrics for the pilot.

Sample Answer

Situation: Our team has been repeatedly firefighting the same incident—service X falls into high-latency state every night and on-call executes ~6 manual steps to restore it. This creates toil, long MTTR, and morale loss.

Project goal: Eliminate/automate the manual runbook so incidents are auto-detected and remediated (or clearly handed off) to reduce MTTR and on-call load.

Milestones:1. Investigate & quantify (1 week) - Collect incident logs, frequency, root cause patterns, current runbook steps. - Measure current MTTR, incident frequency, and toil-hours/week.2. PoC automation (2 weeks) - Build an ad-hoc script that reproduces the manual steps and safely reverses the failure on a staging replica.3. Harden & integrate (3 weeks) - Wrap script as an operator/managed container or integrate with runbook automation (RBA) tool (PagerDuty Rundeck/StackStorm/Argo Workflow). - Add idempotency, locking, backoff, and safe-guards (approval gates for risky actions).4. Testing & rollout (2 weeks) - Run unit/integration tests, chaos tests in staging, and a canary in production during low-traffic window.5. Monitor, iterate & handover (2 weeks) - Observe metrics, reduce rollouts, document runbook, and train on-call.6. Retrospective & project close (1 week) - Compare metrics, capture learnings, propose next automations.

Technical options & when to use them:- Ad-hoc script: Fast PoC and developer-friendly. Use for discovery and staging validation.- Runbook automation (Rundeck/StackStorm/Ansible Tower): Best for safe, auditable, role-based automation and human-in-loop approvals.- Operator (K8s Operator): Best when remediation must act on cluster state continuously and scale; more investment but long-term robust.Choice: Start with script → integrate into RBA for auditability → optional Operator if remediation needs continuous reconciliation.

Mentoring junior contributors:- Pair-program PoC tasks; assign clear small ownership (tests, logging, documentation).- Run weekly checkpoints and code reviews focused on reliability patterns (idempotency, retries).- Provide templates: unit test, integration test, deployment checklist.- Have juniors lead the staging canary with senior oversight to build confidence.

Testing strategy:- Unit tests for logical branches.- Integration tests against a sandboxed environment replicating failure modes.- Chaos/ fault-injection tests to validate automation handles partial failures.- Canary rollout with feature flag and read-only dry-run logs before enabling action.- Post-deploy smoke checks and escalation fallback if automation fails.

Success metrics for pilot (baseline vs 4–8 weeks after rollout):- MTTR reduction (target ≥50%)- Number of manual interventions for this incident (target 0–1/week)- Toil hours saved per week (target measurable reduction)- False-positive remediation rate (target <5%)- On-call alerts suppressed or auto-resolved (count)- Confidence/treasure: On-call satisfaction survey and incident postmortem improvements

Risk mitigation:- Ensure manual override and clear audit trail.- Start with non-destructive actions and escalate permissions gradually.- Implement alerting for automation failures so humans can step in.

This approach balances speed (script PoC), safety and auditability (RBA), and long-term robustness (operator if required), while developing junior engineers through structured mentorship and measurable outcomes.
