2667 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.

  1. Negotiation intermediate

    An architect must agree an integration contract with an external partner whose interests differ. What negotiating approach produces a durable technical agreement?

  2. Presentation Skills intermediate

    An architect must present a genuinely complex distributed training architecture to a mixed audience in twenty minutes. What structure works?

  3. Presentation Skills intermediate

    Review this deck for a 25-minute architecture review: slides 1 to 6 cover the landing zone and network layout, 7 to 18 walk through each microservice, 19 to 26 show the data model, 27 to 31 give the test strategy, and 32 to 34 ask for four engineers for two quarters. The approval has been deferred twice. What would you cut, what would you change, and what would you leave alone?

  4. Sequence Diagrams intermediate

    A checkout sequence diagram has six participants and every arrow is a plain synchronous call with no timeout written on it. In production the fourth participant starts answering in 9 seconds instead of 200 ms and never returns an error. What happens second by second, what stops it, and what should the diagram have carried?

  5. Sequence Diagrams intermediate

    A logistics platform's engineers cannot explain what happens when a delivery is attempted and fails. What communication artefact would help most?

  6. Sequence Diagrams intermediate

    A multi-step order flow with compensations is described in prose and nobody agrees on the behaviour. What does a sequence diagram add, and what must it show?

  7. Sequence Diagrams intermediate

    Two engineers disagree about what happens when a customer cancels an order, and both have been on the team for years. Rather than settle it in the meeting, what do you do, and what will you probably find?

  8. Sequence Diagrams intermediate

    What can a sequence diagram show that a component diagram cannot, and what is the rule for drawing one worth having?

  9. Technical Proposals intermediate Multiple choice

    A team wants to change how search results are ranked on a consumer travel site. The change sits behind a flag and can be reverted in minutes and the guardrail metrics already exist. Which written artefact should they produce to get a decision?

  10. Technical Proposals intermediate

    An engineer's technical proposal for a significant change is repeatedly deferred without a decision. How should the proposal be restructured?

    An engineer's technical proposal is repeatedly sent back for more detail and still not approved. What is usually wrong with its structure?
