How to choose programmers?

[dash121]

Any ideas? I know that to be a successful programmer (at least on our team) you need to have a lot of drive and self motivation. To be able to take a statement such as "tell me about vision tracking" and the rookie programmer be able to go run off and come back knowing "everything about everything". Is there any pre-tests you put your teams (specifically programmers) through to find out if they are going to be a good active members? Lastly, any ideas on how to make those not self motivated to learn?
