2627 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.

84 questions in Software Architecture.

  1. Bounded Contexts advanced

    A payments platform has one Payment entity used by checkout, settlement, refunds, reconciliation and reporting, and it has grown to eighty fields. What is the problem and what is the fix?

  2. Bounded Contexts intermediate

    Review this context map. Eleven bounded contexts, and nine of the relationships between them are shared kernel: a common library of domain types that every team imports and any team may change. The teams report that releases have to be coordinated. What would you change, what would you keep, and how would you argue it?

  3. Bounded Contexts advanced

    Two teams disagree about whether "reservation" and "booking" are one concept or two. What evidence settles it?

  4. CI/CD advanced

    A developer platform's CI system faces a burst of builds after a major release. How should queues, workers, caching and prioritisation prevent collapse?

  5. CI/CD advanced

    A team has a fully automated pipeline and still releases monthly. What is actually blocking them?

  6. CI/CD beginner

    A team's CI pipeline takes 40 minutes. Everyone agrees that is annoying but tolerable, because engineers do other work while they wait. Why does the 40 minutes change what engineers do rather than only how long they wait?

  7. CI/CD intermediate

    Your monorepo runs 320 pipelines a day. Median wait before a runner picks up a job is 11 minutes; the pipeline itself takes 14. Finance asks whether doubling the runner pool is worth $9k a month. Work out the number that answers them.

  8. Clean Architecture intermediate Multiple choice

    A service calls a payment provider over HTTP. The provider occasionally returns 503 and occasionally times out. In a domain / application / adapter layering, which layer should own the retry and backoff policy?

  9. Clean Architecture intermediate

    A team adopts a layered architecture with strict dependency rules and finds every small change touches many files. Is the architecture wrong, or the application of it?

  10. Clean Architecture intermediate

    Review this design. Every repository method opens its own transaction and commits before returning. One use case calls four repositories and then publishes an event. Support reports occasional orders with a payment row and no shipment row. What would you change and what would you leave alone?

  11. Clean Architecture advanced

    When is clean architecture over-engineering, and what is the signal that you have its costs without its benefits?

  12. Code Review intermediate

    A 40-engineer platform organisation requires two approvals on every pull request. Median time from ready-for-review to merge is 26 hours. A staff engineer proposes one approval plus mandatory post-merge review for low-risk changes. What is gained, what is paid, and when does the bill arrive?
