For people who do phone screens, what kind of questions do you ask?
I have shadowed several coding phone screens and I have been simply amazed. All the questions we have asked as basic problems that require OOP programming. Create a class and structure your code cleanly and you should pass. But a lot of people just don't know how to do that. Basic polymorphism is something people just don't do.
I was expecting to do something relatively medium like
this
But thinking of that, I feel like that might be too hard and won't test basic CS concepts and design.
I have seen my colleagues asked people to do stuff like create a minesweeper board, which is pretty straight forward but can easily be expandable. I might ask them to do a tic-tac toe game. Or an address book where you create a program to keep track of people's contacts (phone number, name etc).
