I had a smooth and a bug free experience during an online assessment which I was giving. 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.
