[CodeSignal] felt like a full IDE in my browser. Because I was using Typescript I had IntelliSense and documentation right in the web editor, just like I would have when using an IDE. A lot of other code challenge platforms will just provide you with a plain text editor.

The responsiveness and fluidness of the platform is way above when compared to other platforms. The code evaluation experience is flawless and allows you to concentrate on your tasks as the platform gives a hassle-free experience. Highly recommended.

I liked how many of the IDE features were working smoothly in the code sandbox: bracket highlighting, autocomplete, etc. It felt very intuitive.
