5 interview questions — practise the English for strong Platform SRE responses: golden signals, error budgets, and postmortems.

1 / 5
The interviewer asks: "Explain the four golden signals for monitoring."
Option B is the correct SRE definition with the Google origin and the important nuance about distinguishing successful vs error latency. This shows you've studied the field, not just used monitoring tools.
2 / 5
The interviewer asks: "What is an error budget and how do you use it?"
Option B gives the correct definition, the calculation example (99.9% → 8.7 hours), and — critically — explains HOW it's used (gate deployments). The deployment gate is the key operational insight that separates people who understand error budgets from those who've just heard the term.
3 / 5
The interviewer asks: "How do you measure and reduce toil?"
Option C gives the measurement approach (track manual repetitive tasks), the 50% benchmark, and a prioritisation framework. Option D is incorrect (Google defines toil specifically — not all non-coding work is toil). Showing you know the 50% benchmark signals you've studied SRE practice properly.
4 / 5
The interviewer asks: "What is SLO burn rate and why does it matter for alerting?"
Option C demonstrates deep SRE knowledge: burn rate definition, the rate-1 baseline, example threshold (14x), and the multi-window approach. Mentioning the SRE workbook signals you know the canonical sources. This is an advanced SRE concept that distinguishes strong candidates.
5 / 5
The interviewer asks: "How do you run a blameless postmortem?"
Option C hits all the key elements: focus on systems not people, structured template, psychological safety (and why it matters for data quality), SMART action items, and culture-building through sharing. This is the complete picture of a blameless postmortem, not just the definition.
