What You’ll Be Asked
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.
Topics Covered
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.
Sample 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.
