I've got questions

I am thinking about joining the Caterpillar team, it is something i really want to do but im alittle nervous about the process.
Is there any cat technicians out there who can tell me what the process is like? I heard you have to do an interview which is normal, but also an aptitude test and other things. I am still in school and im interested in working with Cat, so I dont really know much about the process.

also if anyone has any sites or documents they can give me so i can become familiar with Cat products that would be nice, I know a good bit but i dont like to brag so any info would be appreciated, it can also help me out with the interview.

thanks in advance. ;)
