2988 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.

Quiz

A merge queue tests each change against the current trunk plus the queue ahead of it, taking 20 minutes per run and merging serially. 60 engineers each want to merge twice a day. Estimate whether the queue can keep up, and say what you would change first.

A team has a CI system but not continuous integration. What is the difference, and what practices constitute the discipline?

Your CI retries a failed test up to three times before reporting a stage red. Trunk has been green for eleven straight weeks. Twice this quarter a bug reached production that an existing test had in fact failed on, and p50 pipeline duration is unchanged. Where do you look, and what is the diagnosis?
