Usually, it involves hours of scouring through YouTube videos, Medium articles, and blog posts. And even if you find a good practice problem, it's tough to know if you're meeting all the edge cases or have the best solution an employer may be looking for.

“Clientside is AMAZING. The problems are engaging but challenging. It's been a great learning experience and has become a regular study tool for me. The problems are reflective of actual frontend technical interviews, so it never gets old. I would HEAVILY recommend it. "
Engineer at Weavechain
“The exercises are super interactive and come straight from real-life interviews, so it feels like you're really getting a taste of what to expect. Plus, it helped me fill in a lot of the knowledge gaps I didn't even know I had.”

FAQ
How does Clientside differ from other interview preparation resources?
Clientside offers a more practical approach to interview preparation for frontend engineers by providing interactive problems taken from actual frontend interviews, with test suites to check your work against, and senior solutions to learn from, unlike other platforms that mainly focus on algorithm-based problems.
What types of problems does Clientside offer?
Clientside offers a wide range of interactive problems that cover various frontend engineering concepts and technologies, including array builtins, DOM manipulation, debugging, events, game development, reusable functions, state management, and string manipulation. All the problems have varying difficulty levels that range from easy to hard.
Where do you get the problems from?
We scour the internet for other people's experiences from interviews at companies and use these experiences to build our questions. Generally we look at sites like Glassdoor, Medium, YouTube, and Personal Blogs to build out our exercises.
How often are new exercises added to the platform?
We add new exercises to the platform on a weekly basis.
What is included in Clientside Pro Access?
You'll get access to all future platform updates, 120+ interview questions, 600+ unit tests, senior solutions, and new exercises added weekly.
