Interesting concept. As in light, do you mean just a few questions? I agree with the others, it is near impossible for someone to pass that test without the adequate prep. Granted, IMO, most of that prep is learning how to actually take the test and answer the questions, with a little knowledge smattered in. Interesting to me that they would use it as a hiring tool. Could be though, that they are just gauging where you are. Like someone else said, we did that too so that we could focus the class on where the weak spots were. They might just be getting it out of the way during the hiring process.
