Frontend mock interviews
A frontend round rarely stops at "what is a closure". It moves from a small answer to how the browser actually behaves under it, and most candidates lose ground on the second or third follow-up rather than the first question.

What a Frontend round covers
Rendering and the DOM
How the browser turns markup into pixels, what forces a reflow, and why a change that looks cheap in code is expensive on screen. Expect to be asked what happens between a state update and a repaint.
State and data flow
Where state should live, what makes a component re-render, and how you would explain a stale-closure bug to someone who has just hit one. Framework-specific follow-ups depend on the stack you pick.
The event loop and async
Microtasks against macrotasks, why a promise resolves before a timeout, and how you would debug an interaction that feels janky without reaching for a profiler first.
Accessibility and semantics
The part most candidates skip. Choosing the right element, keyboard behaviour, and what a screen reader announces — asked as a design decision, not as trivia.
What the interviewer is listening for
Interviewers are listening for whether you can move between levels: the API you use, the mechanism underneath it, and the trade-off you accepted. Naming the trade-off out loud scores better than an answer that quietly assumes it.
Where candidates lose marks
- Reciting a framework API without being able to say what it does underneath.
- Going quiet while thinking, so the interviewer cannot tell whether you are stuck or working.
- Treating accessibility as an afterthought when asked to build a component.
Two ways to practise
An AI round, on your own
One question at a time with real follow-ups on what you actually said. Choose three, five or eight questions. Scored the moment you finish, with a written breakdown across technical depth, problem solving and communication.
A live mock with an engineer
Forty minutes over Zoom with someone who runs frontend interviews for a living. They score five criteria and write up what to fix, and you keep a numbered certificate for the session.
Pick your stack for an AI round: React · Angular · JavaScript · HTML · CSS · React Native.
