Mistakes to Avoid

BAD: “I’ll just list SLO definitions.” GOOD: Cite the exact SLO target you’d set (e.g., “99.9 % latency < 200 ms”) and explain how you’d adjust it when the error budget exceeds 5 %.

BAD: “My design is a generic sharded store.” GOOD: Reference the specific service (e.g., “DynamoDB‑style partitioning with consistent hashing”) and tie it to the 100 k QPS metric the interviewer gave.

BAD: “I’m comfortable with any reliability framework.” GOOD: Show you understand Google’s “four‑pillar reliability taxonomy” and Amazon’s “four‑step operational excellence checklist” and apply the appropriate one to the scenario.

FAQ

What if I only have time to read one resource? Read the Google SRE Book first; the HC consistently rewards deep SLO knowledge over Amazon‑specific tooling.

Do I need to know the exact compensation numbers to negotiate? Yes. Google’s SRE offers in 2024 average $210k–$225k base; Amazon’s average $215k–$230k base. Mention the precise figure to anchor negotiations.

Can I skip the post‑mortem two‑pager and still pass? No. The hiring committee’s “Strategic Automation” signal requires a concrete post‑mortem format; without it, candidates typically receive a 2‑5 vote to reject.amazon.com/dp/B0GWWJQ2S3).
