Accessibility (a11y) QA Interview Prep
Accessibility QA interviews test whether you can make products usable for people with disabilities and verify conformance to standards. Expect questions on WCAG, screen-reader and keyboard testing, ARIA and semantics, and balancing automated checks with essential manual testing.

What does the Accessibility QA Engineer interview look like?
Expect questions on the WCAG principles (perceivable, operable, understandable, robust) and conformance levels (A, AA, AAA), how you test with screen readers (NVDA, VoiceOver, JAWS) and keyboard-only navigation, and how ARIA roles and properties should and should not be used (the first rule of ARIA: do not use ARIA if a native element works). Interviewers want to see that you know automated tools (axe, Lighthouse, WAVE) catch only a fraction of issues, perhaps 30 to 40 percent, so manual testing with assistive technology is essential. Topics include color contrast, focus management, accessible names, and testing dynamic content and single-page apps.
Which topics come up in Accessibility QA Engineer interviews?
Core areas interviewers evaluate for Accessibility QA Engineer roles.
WCAG & Standards
The POUR principles, conformance levels A/AA/AAA, and how success criteria map to real checks.
Screen Readers
Testing with NVDA, VoiceOver, and JAWS, accessible names, and how content is announced.
Keyboard & Focus
Keyboard-only navigation, focus order and visibility, focus traps, and skip links.
ARIA & Semantics
Native HTML first, correct roles and properties, and the traps of misusing ARIA.
Automated + Manual
Why axe/Lighthouse catch only part of the issues and where manual assistive-tech testing is essential.
Dynamic & Mobile a11y
Testing SPAs, live regions, and mobile accessibility across platforms.
What are common Accessibility QA Engineer interview questions?
Questions based on real Accessibility QA Engineer interview patterns. Practice answering these with AssertHired’s AI interviewer.
- 01
Walk me through the WCAG principles and conformance levels. What does AA mean in practice?
- 02
How would you test a feature with a screen reader, and which readers would you use?
- 03
How do you test keyboard accessibility, and what are common focus-management bugs?
- 04
When should you use ARIA, and what is the first rule of ARIA?
- 05
Automated tools pass a page. Why is it still not necessarily accessible?
- 06
How would you test that a single-page app announces dynamic content updates?
- 07
How do you check and fix color-contrast issues?

Common questions about Accessibility QA Engineer interviews
Can accessibility testing be fully automated?
No. Automated tools like axe and Lighthouse reliably catch only a portion of issues (often cited around 30 to 40 percent), things like missing alt text or contrast. Many criteria, meaningful labels, logical focus order, sensible screen-reader experience, require manual testing with assistive technology.
What is the difference between WCAG levels A, AA, and AAA?
They are conformance levels of increasing strictness. A is the minimum, AA is the common legal and practical target for most organizations, and AAA is the most stringent and not always achievable for all content.
What is the first rule of ARIA?
Do not use ARIA if a native HTML element or attribute already provides the semantics and behavior you need. Native elements are more robust; ARIA is for when no native option exists.
Can I practice accessibility QA questions on AssertHired?
Yes. The AI interviewer asks WCAG, screen-reader, and ARIA testing questions with follow-ups and scores you across four dimensions.
