Codility offers solid best practices for interviews. I find their approach to be effective and helpful during the interview process.

It provides all the essential features without any extra fluff

I like Codility for its seamless coding interviews and live coding sessions, which allow me to see how candidates evolve their code. The interface is easy to use, making it straightforward to create new tasks, run code, and see the output in the console. It's especially convenient when candidates can choose their preferred programming language, and I can instantly set up a corresponding task in that language. Codility significantly impacts efficiency with its live code execution, better than platforms like CoderPad.
