Accessibility Testing Interview Questions
Accessibility testing is no longer optional, it's a legal and ethical requirement. Practice with an AI interviewer that asks about WCAG conformance levels, ARIA semantics, automated a11y scanning, and manual screen reader testing.

What do interviewers ask about Accessibility Testing?
Accessibility testing interviews focus on your practical knowledge of WCAG 2.1 and 2.2 success criteria, the difference between Level A, AA, and AAA conformance, and how to use tools like axe-core, Lighthouse, and WAVE. Expect scenario-based questions about diagnosing color contrast failures, fixing keyboard traps, and writing ARIA attributes correctly. Senior roles will probe your experience integrating a11y checks into CI/CD pipelines and remediating audit findings at scale.
What do Accessibility Testing interviewers ask at junior, mid and senior level?
The same tool, three different interviews. Find your row before you prepare.
| Level | What interviewers probe | Typical question |
|---|---|---|
| Junior | What interviewers probeWhat WCAG is, the four principles, common failures like missing alt text and low contrast, and using a browser extension to check a page. | Typical questionName three accessibility problems an automated scanner catches and two it usually cannot. |
| Mid-level | What interviewers probeIntegrating axe into automated suites, keyboard navigation testing, screen reader basics, and writing a defect a developer can act on. | Typical questionHow would you add accessibility checks to an existing Playwright or Cypress suite without doubling its runtime? |
| Senior | What interviewers probeAccessibility as a release gate, legal exposure and standards, auditing a legacy product, and building capability across the team. | Typical questionA product has never been audited. How would you scope, prioritise and staff the accessibility work? |
Which Accessibility Testing topics come up most?
Key areas interviewers evaluate when asking about accessibility (a11y).
WCAG 2.1 & 2.2 Standards
Understanding POUR principles (Perceivable, Operable, Understandable, Robust), conformance levels, and key success criteria like 1.4.3 and 2.1.1.
Automated A11y Tools
Using axe-core, Lighthouse, WAVE, and pa11y to catch accessibility violations early in development and CI pipelines.
Screen Reader Testing
Testing with NVDA, JAWS, and VoiceOver, understanding how assistive technology interprets the DOM and ARIA roles.
ARIA & Semantic HTML
When to use ARIA roles, states, and properties versus native HTML semantics, and the first rule of ARIA.
Color Contrast & Visual
Color contrast ratios (4.5:1 for text, 3:1 for large text), focus indicators, and accommodating low-vision and color-blind users.
Keyboard Navigation
Ensuring full keyboard operability, focus management, tab order, skip links, and avoiding keyboard traps.
What are common Accessibility Testing interview questions?
Questions based on real interview patterns. Practice answering these with AssertHired’s AI interviewer.
- 01
Explain the difference between WCAG Level A, AA, and AAA. Which level do most organizations target and why?
- 02
You run axe-core on a page and it reports zero violations, but a screen reader user still can't complete a form. What could be wrong?
- 03
What is the first rule of ARIA and how does it influence your approach to accessible markup?
- 04
How would you test a single-page application for keyboard accessibility? Walk me through your process.
- 05
Describe how you would integrate accessibility testing into an existing CI/CD pipeline.
- 06
A designer hands you a mockup with light gray text on white background. How do you evaluate and communicate the accessibility issue?
- 07
What are the key differences between axe-core, Lighthouse, and manual screen reader testing? When do you use each?

Frequently Asked Questions
What accessibility testing topics come up most in QA interviews?
WCAG conformance levels, the POUR principles, axe-core and Lighthouse usage, ARIA best practices, keyboard navigation testing, and color contrast ratios are the most commonly asked topics. Interviewers want to see that you can both run automated scans and perform meaningful manual testing with assistive technology.
Do I need to memorize every WCAG success criterion?
No. Focus on the most impactful criteria: 1.1.1 (non-text content), 1.4.3 (contrast), 2.1.1 (keyboard), 2.4.7 (focus visible), 4.1.2 (name/role/value). Understanding these deeply is more valuable than memorizing all 78+ criteria at surface level.
Is accessibility testing a growing area in QA?
Yes. With increasing ADA and EAA enforcement, accessibility testing skills are in high demand. Many companies now require a11y testing as part of their definition of done, and roles specifically focused on accessibility QA are becoming more common.
Can I practice accessibility testing questions on AssertHired?
Yes. AssertHired's AI interviewer asks practical questions about WCAG compliance, a11y tooling, screen reader testing, and integrating accessibility into your test strategy. You receive scored feedback across four dimensions.
Which Accessibility Testing terms should you know?
Concepts interviewers expect you to define alongside Accessibility (a11y).
