Apple Front End Interview Questions

Full guide on GreatFrontEnd

Explore round details, preparation advice, and related practice in GreatFrontEnd's Apple Front End Interview Guide.

Apple's frontend interviews differ across teams. Experiences include small React screens, vanilla-JavaScript tasks, CSS implementation, and full-stack design. Confirm the team's scope before assuming that another applicant's sequence will match yours.

JavaScript coding questions​

  • Implement Array.prototype methods (flat, map, reduce, concat) by yourself using JavaScript.
  • How can you execute an array of promises in sequence?

User interface coding questions​

  • Implement a simple photo ordering tool with vanilla JS and no libraries.
  • Build a progress-bar groups component (phone-screen variant — no animation).
    • The animated Progress Bars exercise is related practice; the candidate's screen did not require animation. (Free)
  • Implement a multi-step form where navigation passes data between steps. Redux was required in one senior full-stack candidate's round; confirm the state-management constraints for your own task.
  • Achieve a masonry layout like Pinterest (CSS-focused round).
  • Build a basic to-do app in React (smaller phone-screen variant).

System design questions​

  • Design a database schema (full-stack flavored round; the interviewer may give you the option to deep dive into frontend or backend afterwards).
  • Design Pinterest (masonry feed).

Quiz questions​

  • How do you build an npm package?
  • What is a compositing layer in CSS?

Algorithm​

  • Given an array, return an array where each value is the product of the next two items: E.g. [3, 4, 5] -> [20, 15, 12]

Insider tips from the GreatFrontEnd community​

These tips were shared by GreatFrontEnd users who have completed interviews with Apple.

September 2025:

For Apple you really have to study everything, including DSA / LeetCode. Their questions started with a base problem and they pulled concepts from other problems as follow-ups. Pattern recognition is key — if you can map a question to one you've seen before, you have 75%+ of the problem solved.

I personally wouldn't go into any Apple interview without at least the Blind 75 under my belt. If you get a DSA round and can't pass it while other candidates can, you're usually done. Candidates today are too strong — the bar is genuinely high.

August 2025:

... a React phone screen plus 4 onsite rounds — database schema design, React coding, behavioral, plus one more very Apple-specific round. ... I was interviewing for senior full stack. Phone screen felt similar to a "progress bar groups" question without the animation. Onsite React was like a multi-step form with nav passing data (Redux required). One round was CSS-specific — achieve a masonry-like Pinterest layout.

May 2025:

in final rounds with apple, this is what recruiter explained

There will be 4 x 45 min interviews conducted virtually so can be on 1 day or split over 2. See below for focus areas.

JavaScript: Coding (similar to tech screen) Bug Hunt: Coding (working on existing code base) Web Performance (Domain knowledge questions focused on Web Performance) Product Thinking (Behavioral round focused on collaboration, balancing technical VS business needs and understanding user impact)

if anyone has tips for how to practice / prepare for "bug hunt" and "product thinking" feel free to comment. i believe "web performance" will be deep JS trivia likely covering a range of concepts that are usually surfaced in FE system design interviews

December 2024:

they have a big question bank, usually team by team case yes they ask sys design, its a faang company so the bar is really high

April 2024:

Think it was 6 total rounds All fundamentals Vanilla js

(In response to what do you think helped you prep for: big tech, specifically apple is asking a lot of vanilla js questions, dom related questions?) GreatFrontEnd UI questions all with vanilla js implementation

April 2024:

They don’t like to ask LC questions but rather asked my background and experience with 10 mins left for a super easy js question. ... the process really depends on the team you are about to interview for.
