Software Engineer at QueryLayer

Solving Leetcode puzzles might be great for learning algos but it won't prepare you for frontend interviews and it doesn't teach you anything about React internals. Clientside is an incredible solution and I have been recommending it to the developer community every time someone mentions practicing front-end.

Software Engineer at Hubspot

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.

Engineer at Weavechain

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.

Frontend Engineer

I have worked as a front-end developer for two years, yet I still find some of the "Easy" questions to be challenging… I highly recommend Clientside to anyone who is interested in tackling more practical coding challenges.
