Top 7 SRE Interview Questions Every Candidate Should Master
This article outlines the seven most important Site Reliability Engineering interview questions, explains why they matter, and provides an overview of the upcoming SRE Foundation course that equips professionals with the principles, practices, and tools needed for reliable, scalable systems.
Beyond technical skills, Site Reliability Engineering (SRE) helps balance trade‑offs and pressures to achieve fast, safe delivery, acting as a cultural and practical bridge between development and operations.
Question 1: How do you decide whether the team should develop new features or pay down technical debt?
This question lets SRE candidates demonstrate how to handle seemingly conflicting priorities by establishing shared priorities that the team can agree on and act upon.
Question 2: How do you set SLOs and SLIs, and adjust them when necessary?
SRE’s core responsibility is defining and refining Service Level Objectives (SLOs) and Service Level Indicators (SLIs), especially when developers lack visibility into the performance baselines of the services they build.
Question 3: Which of the three observability pillars (logs, metrics, traces) is most important to you, and what would you increase exposure for?
Observability—comprising logging, metrics, and tracing—is fundamental to SRE and a data‑driven discipline essential for any reliability role.
Question 4: How have you implemented process improvements or other changes in the past?
Even when existing monitoring practices, call‑out procedures, and standard processes exist, SREs should challenge the status quo, requiring creativity and resilience.
Question 5: How do you balance the wishes and needs of different stakeholders within the team?
Upstream (development) and downstream (operations) tasks, processes, and procedures must be understood and, when necessary, altered, recognizing that owners may protect existing practices.
Question 6: How do customer experience and/or employee experience influence your SRE strategy?
The best SREs translate external perspectives—customer and employee experiences—into reliable observability and monitoring strategies that evolve into proactive reliability practices.
Question 7: How do you stay current with industry trends and toolchains?
Continuously learning new technologies and approaches is essential for solving old problems with fresh solutions.
The above seven questions are the key topics SRE interviewers focus on. The SRE Foundation course will launch at the GOPS 2021 Global Operations Conference in Shenzhen (May 19‑20).
The course introduces SRE’s evolution, future direction, and provides practical methods and tools to embed reliability across the organization, using real‑world cases. Graduates will be able to set and track Service Level Objectives (SLOs) in their companies.
It also prepares learners to pass the SRE Foundation certification exam.
