2908 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

6 questions in Quality Gates.

  2. Quality Gates advanced

    A security vendor's release process gates sensor code behind staged rollout with canaries, and ships detection content through a separate path validated by a content checker and pushed to every customer within minutes. In July 2024 CrowdStrike's own root cause analysis describes exactly this shape, and a mismatch between 21 fields supplied and 20 fields read produced an out-of-bounds read that crashed around 8.5 million Windows hosts. Review the process. What would you remove, what would you add, and what would you leave alone?

    Your CI suite fails about one run in four, and roughly 80% of those failures pass on a re-run. Developers now re-run by reflex, including on real failures. JetBrains ships flaky-test detection in TeamCity based on flip rate. Design the gate, and say what you refuse to do.
