2827 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.

2827 questions.

  1. API Error Handling intermediate

    A public API's errors are a mixture of HTTP status codes, free-text messages and inconsistent bodies. Design an error contract that integrators can automate against, and explain what each part is for.

  2. API Error Handling advanced

    A shipping aggregator integrates dozens of carriers whose APIs report failures inconsistently - some with HTTP codes, some with 200 and an error body, some with a timeout that means success. How should errors be modelled?

  3. Estimation intermediate

    An architect is asked how long a migration will take and has genuinely no basis for a number. How should estimation be approached so the answer is useful rather than either false precision or a refusal?

  5. Estimation intermediate

    An architect must estimate a large piece of work with genuine uncertainty. What makes an estimate useful rather than misleading?

  7. Estimation advanced Multiple choice

    Your capacity plan sizes the platform at twice last year's peak. Ticketmaster's November 2022 Eras Tour onsale took 3.5 billion system requests - four times its previous peak - after inviting 1.5 million verified fans. Which assumption inside a peak-multiple estimate fails first?

  8. Ethics in Architecture intermediate Multiple choice

    A consumer app logs full request and response bodies for 30 days to chase a client bug. The bodies contain home addresses and partial payment identifiers. Which change most reduces foreseeable harm?

  9. Ethics in Architecture advanced

    A product's growth team wants account deletion to take 30 days of "cooling off", during which the account is recoverable and the user receives win-back emails. The architecture already implements this as a soft-delete flag. What happens when the first erasure request arrives citing a legal right, and what should have been designed differently?
