<human>: Can you summarize the given text in a few sentences?

I saw a post on Craigslist a few weeks ago for a job preparing high school students to transition to college. "Oooh!" I said. "I am totally qualified for this!" The description mentioned that you get a bonus for each student you get to sign up for the program, which I thought was a little sketchy, but I applied anyway. 

Today I got an email from them saying that they've chosen me (and a few others) from among hundreds of applicants. To move forward, I need to sign a non-disclosure agreement and then have a skype interview (as far as I can tell, they're based in a city about 3 hours away). I looked through the non-disclosure agreement, and it basically says that they're going to be giving away company secrets during the course of the interview, and I have to agree not to tell anyone any of this for 5 years. 

I'm worried that this company is charging parents a fortune and not really giving the students any good advice or training, and also that they they're using their employees to get new customers. 

They have a website, but it's currently down, and the Google Cache just shows a pretty boring front page, with no mention of pricing or content. The email they're using is from gmail, which doesn't exactly inspire confidence. I can't find any information on them on the web, which could be good or bad.

If this is legit, it's exactly what I'd like to do this summer, but my spider-senses are tingling. Anyone have any thoughts?
<bot>: I've been offered a job with a company that seems a little sketchy, and they want me to sign a non-disclosure agreement before they'll even interview me. Should I do it?
