I still find a big part of coding interviews to be just looking at the quality of someone's code. The problem I've used for years as a take home coding test is not intended to be a test of ability to implement any particularly complex algorithms or to solve unfamiliar problems on the spot but more to see how people write code in the small. Many candidates still don't make a great showing on the basics unfortunately.
