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.

2627 questions.

  1. Accessibility Architecture advanced

    Where should accessibility live architecturally so it is not a remediation project every year?

  2. Accessibility Testing intermediate Multiple choice

    A public-sector organisation runs 40 services on a shared component library and must meet WCAG 2.2 AA. An automated scan in each service's pipeline reports no violations, and an external audit finds 60 issues, most of them keyboard traps and focus-order problems in shared components. Where should the verification effort be placed?

  3. Accessibility Testing intermediate

    Review this setup at a ticketing platform in the mould of Ticketmaster. Every design-system component carries unit tests plus an automated accessibility check and all of them pass. The queue page announces "you are number 12000 in line" through a polite live region updated every two seconds. An external audit fails the checkout flow on focus order and on announcements. What would you change, and what would you leave alone?

  8. Architecture Decision Records intermediate

    An interviewer asks you to pick an architectural decision your team made in the last year and write its decision record on the whiteboard, then hands you a fact partway through that would have changed the choice. What is being assessed, and how should you work through it?

  9. Architecture Decision Records intermediate

    Review this decision log. It holds 140 records over four years in the repository. 31 are marked superseded and 9 of those name no successor. Two records state conflicting positions on the same message bus and both read "accepted". The template has a Consequences heading that is empty in 96 records. A new engineer asked what the current position on async messaging is and spent half a day finding out. What would you change, what would you remove, and what would you leave alone?
