Hey there,
Be careful. They almost suckered me last week! I'm very lucky that I brought it up that "I have a job interview in a couple hours" to my friends, and they watched out for me. Vector had called me just an hour before and scheduled the interview for a couple hours later... I canceled the interview right after my friends informed me.
The interview will be a group interview. Most of the people there will get hired. You will then attend 3 days of unpayed training, where they will teach you to read off a script to sell overpriced knives. You'll make a list of your friends and family and their phone numbers. It'll sound like an activity, but these are actually the people you will be selling to. Basically, they want to get 900-1200 from your immediate family (they'll assume your immediate family will give in just to help you with your new job) and hope to leech some off of your other family. This is exactly why they target incoming college students.
You'll have to make appointments to go to peoples' homes and tell them about the knives and try to sell to them. Vector pays nothing to help you, including gas nor phone time. Under vector, you are an "independent contractor," so they don't pay anything as a business expense for you.
Just a warning. I recommend you read this (all of it; I did):

It's amazing how aggressive the vector lovers become in these threads. You can be sure that they were paid by vector.
Please check these video documentary-ish youtube clips, too:

And this is how to cancel your interview (I did essentially the same thing)

Just looking out for you, my fellow knifeknut.
