Site Reliability Engineer interview questions

Short answer

A Site Reliability Engineer interview usually covers three areas: behavioral questions about past work (answered with the STAR method), technical questions about Kubernetes, Linux, monitoring, and your questions for them — which you should always have. The single most likely question is "Tell me about a time you improving uptime and meeting SLOs."

The STAR method

Behavioral answers are expected in this structure:

Situation

One line of context

Task

What you were responsible for

Action

What you actually did — about 60% of the answer

Result

A number: %, time saved, revenue, users

Behavioral questions

“Tell me about a time you improving uptime and meeting SLOs.”

This is the core of the role, so expect it. Use STAR: one line of context, what you specifically did, and a quantified result.

“Describe a situation where calm under pressure changed the outcome of a project.”

Pick a real moment of friction. Spend most of your answer on the actions you took, not on adjectives about yourself.

“Walk me through a project where you had to reducing incident frequency and MTTR.”

Goal → your role → the obstacle → the measurable result. Keep it under two minutes.

“Tell me about a time something went wrong. What did you do?”

Never claim you've made no mistakes. Choose a real one and focus on the recovery and the process change afterwards.

“Why this role, and why now?”

Connect something specific about the company or team to the work you want to be doing more of.

Technical questions

Prepare one concrete example for each of your core skills.

“How do you approach improving uptime and meeting SLOs?”
“What's your hands-on experience with Kubernetes? Give a specific example.”
“What's your hands-on experience with Linux? Give a specific example.”
“What's your hands-on experience with monitoring? Give a specific example.”
“What's your hands-on experience with Prometheus? Give a specific example.”
“What's your hands-on experience with Grafana? Give a specific example.”
“How do you measure success in a Site Reliability Engineer role?”
“How do you prioritise when several things are urgent at once?”

Questions to ask them

Saying "no, I don't have any questions" costs you. Prepare two or three:

“What does success look like for this Site Reliability Engineer in the first 90 days?”
“How is the team handling improving uptime and meeting SLOs today?”
“What's the biggest challenge facing the team right now?”
“How would you describe the team's working style?”
