The goal of this guide is to help you prepare and practice for your next Frontend job interview. We have curated this list of resources to keep it as impactful as possible. The learning resources are mostly focused around JavaScript, but the practice questions cover the entire Frontend spectrum.
This guide is targeted specifically to Frontend roles in the industry. There are resources about JavaScript, CSS, HTML, and general Frontend knowledge. We've also included introductory Data Structures and Algorithm questions. Not all companies interview Frontend developers the same way -- that's why we also created How Companies Hire to give you an insight into how to prepare for the specific company you're applying for.
When it comes to preparing for interviews there's no real secret. You have to learn the material and practice.
