Frontend interviews go deeper than React. Expect questions on browser APIs, performance budgets, accessibility, CSS architecture, and building UIs that work for everyone.
Sample questions
These are the kinds of questions you'll drill. Real mock rounds will generate many more — tailored to the exact JD you paste in.
How would you optimise a page that scores 40 on Lighthouse performance?
Explain the critical rendering path and how it affects perceived load time.
Walk me through making a complex interactive component fully accessible.
How do you decide between client-side and server-side rendering for a feature?
Describe your approach to CSS architecture in a large application.
Reading Frontend Developer questions isn't the same as answering them live. You need the rep — the pause, the clarifying question, the moment where you realize you forgot the framework. We put you in that exact spot, then show you what a strong answer would have looked like.
