The problem is that there are some people who are very, very good at bullshitting. They can talk the talk - but not walk the walk. I've had several occasions where somebody I was sure would ace the coding has fouled up badly. And not "little bit nervous" badly, but "wow - you have put significant effort into learning how to lie during an interview" badly. One was early in my career, when I didn't do coding tests, and they got hired. It was an expensive mistake. I've encountered enough of 'em to want to stop myself ever making that mistake again. Never hire a juggler without seeing them juggle (http://raganwald.com/2006/07/hiring-juggler_02.html http://raganwald.com/2006/07/hiring-juggler_02.html).
