What’s this site?

This site is a repository of questions for frontend engineer job seekers looking to test themselves prior to going into interviews (or if you’re just looking for a challenge to level up your skills).

What makes this site different from other interview prep resources?

At many companies, algorithmic interview questions have fallen out of favor when hiring frontend engineers. The reason is obvious: these questions are nearly worthless when it comes to evaluating how well a frontend engineer can do their job. Companies have begun shifting towards practical questions that test actual frontend skills, like implementing UIs, creating interactive features, doing so in an accessible and performant way, etc.

While the evolution towards more practical evaluation is generally a positive trend, it doesn’t help you much when it comes to your interview prep. Most interview prep resources are geared towards algorithmic interviews. Usually the most you’ll get is that you can do the algorithmic interview exercises in JavaScript/TypeScript. This site is built to give you practice with more of the practical exercises you’ll encounter in modern frontend interviews.

This site was built by three engineers, from the West Coast (Bay Area) to the East Coast (NYC). Our team consists of a current-Airbnb frontend engineer, ex-Google, ex-Airbnb frontend engineer, and an Amazon frontend engineer. We started this project out of our own frustration towards the lack of frontend-specific interview resources. We’ve done plenty of interviews in our time, securing offers in recent years from companies like Lyft, Stripe, Square, and Netflix, and are hoping to share some of our interviewing expertise with you.
