CodeSignal is popular website hosting coding challenges aimed at helping people familiarize themselves with coding-interviews. Many challenges are from Google, Amazon or other FAANG companies. Here is a list containing some of the many challenges I have solved. As of now, most solutions are written in Rust, but in my CodeSignal account you can find solutions written in other programming languages too.
