Top 4 Wcag Interview Questions
Browse 4 real-world technical and behavioral interview questions about Wcag. Review scenarios, edge cases, and architectural best practices.
A modal passed design and QA review, but keyboard users report they can tab out of it into the page behind, and once they do they cannot get back or close it. Diagnose it and tell me what a correct dialog does.
The dialog was built as a styled div, so nothing marks the rest of the page inert. Focus was never moved in, never constrained, never restored on close, and Escape was never wired. A correct dialog moves focus in, keeps it in, restores it, marks background inert and is labelled - which native dialog with showModal gives you almost for free.
How do you implement a scalable architecture and tooling to automatically enforce strict WCAG 2.1 AA compliance across dozens of autonomous frontend teams without crippling developer velocity?
Assess the candidate's capability to shift accessibility left through automated enforcement pipelines, inherently accessible design systems, and systemic remediation strategies at scale.
This form marks invalid fields with red text and a red border. What has to change?
Accessible form errors need visible text, programmatic association with the field using aria-describedby, aria-invalid for state and deliberate focus handling after submit. Use this accessibility answer to show the decision, trade-off, and evidence rather than a memorised definition. It also connects FORMS to the point an interviewer is testing.
Design rejected the native control, so you are building a custom one. How do you make it accessible?
An accessible custom interactive component should start from the nearest native element, preserve keyboard and focus behavior, and use ARIA only for state that HTML cannot express.
