| Key topics | Linux internals, TCP/IP & DNS, Error budgets, Capacity planning, Incident response |
Google Site Reliability Engineer Technical Interview Questions
Expect Site Reliability Engineer-focused technical questions such as:
- Explain SLI, SLO, SLA, and error budgets
- Debug high latency in a service (step by step)
- What happens when you type a URL and hit enter?
- Design a monitoring and alerting system
- How do you handle a cascading failure?
- Write a script to parse and aggregate logs
Google also emphasizes Data structures & algorithms and Graphs & dynamic programming, so be ready for questions like:
- Find the shortest path in a weighted graph (Dijkstra)
- Return all valid word breaks of a string (DP + trie)
- Design and implement an LRU cache
Google Behavioral Questions
- Tell me about a time you worked with ambiguity
- Describe a project where you disagreed with a senior engineer
- How do you handle receiving critical feedback?
How to Prepare for the Google Site Reliability Engineer Interview
- Know Linux, networking, and reliability concepts
- Practice structured troubleshooting out loud
- Understand SLOs and error budgets
- Practice on a plain editor — phone screens use Google Docs
