Google SRE candidates report a recruiter call, coding rounds that may be written in a plain Google doc, Linux and reliability design questions, and a Googlyness assessment. Leveling and team matching can follow the loop.

Candidates describe the Google SRE interview as a mix of software engineering and systems depth, so preparing for only one side is risky. On the coding side, one candidate wrote a memory-heavy editor problem in a plain Google doc with no autocomplete or run button. Another needed to start with brute force and then reach the optimal solution after a hint. Practice narrating your progression from brute force to optimal and coding without tooling.
On the systems side, one candidate was asked what an inode is, and said other questions stayed on file behavior, so filesystem internals are worth reviewing beyond everyday commands. The same candidate got an open-ended prompt about keeping a system reliable when servers crash or become overloaded. They began by defining what reliability meant for the service. Another candidate was given vague case studies where the interviewers cared about how they reasoned through ambiguity.
Behavioral and leveling signals matter too. One L5 candidate says a mistake in one section of a design round was enough for the committee to level them down to L4. They also suspect their Googlyness round was mixed because they kept their answers polished and avoided committing to a real position. Be ready to take a clear stance in behavioral answers rather than playing it safe. Outcomes in these reports were an offer that was declined, a downlevel that was declined, a rejection, and one pending decision. Ask your recruiter what policies apply before and after the loop.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports the process starting with a recruiter reaching out about a Software Engineer, Site Reliability role. They described the first call as friendly and clear about expectations. It is worth confirming which flavor of SRE the team hires for, since another candidate noted that some loops lean toward Linux and data center operations.
One L4 SWE-SRE candidate reports a phone screen with a coding round that they felt leaned positive. Another candidate's single technical round was built on vague case studies, where reasoning through ambiguity mattered. The coding in that round was done in a Google doc rather than an IDE. Rehearse speaking your assumptions aloud before you write code.
The L4 candidate describes two onsite coding rounds. In the first, a hard problem, they wrote brute force first and needed a hint to reach the optimal approach. They rated the second round as stronger. Expect the interviewers to follow how you progress, so practice explaining tradeoffs and moving from a simple solution to an efficient one.
One candidate reports an open-ended design prompt about staying reliable when servers crash or become overloaded, plus low-level Linux questions such as what an inode is. Another, interviewing at L5, says a mistake in one design section was enough for the committee to level them down. Define reliability goals first, and take extra care on the sections where you are less sure.
One candidate suspects their Googlyness round was mixed because they gave polished, safe answers without committing to a real position. Decisions may take weeks. One candidate was still waiting more than two weeks after the onsite, and another was offered a team match at a lower level than they interviewed for. Ask your recruiter about timing and any reapplication policy.
