Site Reliability Engineer Interview Experience at Salesforce – 2025

The coding challenge allows any programming language, and Python's concise standard library tends to be a strong choice. The challenge tests basic programming and problem-solving skills relevant to system automation tasks specifically — candidates are given a set of unstructured log lines and asked to extract structured fields (timestamp, severity, service name) using regular expressions, then aggregate error counts per service over a rolling time window.

This Linux-focused round tests practical knowledge and command-line skills over memorized theory, matching the real reported structure closely. One confirmed real question from this loop: what command would you use if you wanted to find a file but did not know its location. A strong answer covers both `find` (searches the filesystem live, always current but slower) and `locate` (queries a prebuilt index, much faster but can be stale if the index hasn't been updated recently), walking through scenarios where each would be the better choice.

This resume-based interview involves the interviewer reviewing the candidate's CV and work experience in detail, asking for justification of specific technical decisions from past projects rather than just a description of what was built. A common deep dive covers a monitoring setup previously implemented — specifically why particular alert thresholds were chosen and how they were validated as not producing excessive false positives before rolling out to the full on-call rotation.
