Who is this Site Reliability Engineer (SRE) interview plan for?

It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Technical Interview round for a Site Reliability Engineer (SRE) role. It gives you a 60 min script to follow in the conversation — 10 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.

What does the Technical Interview round assess?

This round is focused on: Reliability Engineering, System Performance, Monitoring Tools, Capacity Planning, Automation. It works through Introduction, Reliability Engineering, System Performance and Monitoring Tools, Automation and Problem-solving, Collaboration Skills and Closing, scoring against 65 observable signals, with follow-up prompts on all 10 questions for going deeper where an answer is thin.

How is the 60 min split up?

Introduction (5 min), Reliability Engineering (10 min), System Performance and Monitoring Tools (10 min), Automation and Problem-solving (10 min), Collaboration Skills (10 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.

What other rounds should I run for a Site Reliability Engineer (SRE)?

A single round does not cover a whole role. The other rounds in this library for a Site Reliability Engineer (SRE) are Behavioral Interview, Coding Test, Incident Management Q&A, Reliability Scenario Discussion and System Design Interview. Each is a separate plan you can use as it is.
