Thanks man...yeah I got that book. The reason I am concerned is because I got an email immediately after applying asking for further information to fill out their tax credit & EEO information. When I clicked on the link in their email and attempted to fill it out it said that they already had it on file from a previous application. So I was unable to do it....now my application status is stuck on "need more information".<quoted text>
I think it took about a week or so to get the invite, I wouldn't worry they are probably just waiting to fill up their list of applicants and schedule the groups.
I would recommend using your time now to study for the test, the best book I found is called "Barron's Mechanical Aptitude & Spatial Relations Test", also memorize the 25-pair wire color code and brush up on your basic electrical circuit knowledge.
Oh well I'll just wait a bit longer and see what happens...thanks
