For coding interviews, the company could make an application form that gives you three simple coding exercises, the submitted code is automatically tested, and when the tests pass you are asked to upload your CV. When you come to the company, you get two more coding exercises of the same difficulty, if you pass at least one of them, you can talk to a human. (This last step is to turn away the candidates who asked someone else to do the exercises for them.)
