Hey, I need your guy's help!

From what that sounds like, basically if you say yes, you will be subject to stuff that you can't talk to the public/press/friends about, lest they leak that stuff out before the company is ready to roll out something.

The non-compete clause sounds like "if you work for us, then you can't work for our competition if you quit our company for like 5 years or so".

As for the other two, I think they kind of go together. For example, let's say you're applying for a video game company. They have a non-disclosure agreement that says they're coming out with "Game X". Until the producers feel the game is ready to be shown to game magazines/public, you're not to talk about the game with anyone outside of the company, and if you do, and word gets out that it was you who leaked the information, you can be fired for that, and maybe sued, depending on what kind of info you broke out (most likely they'd say "breach of contract" and you hurt their business as a result of that).

I'm guessing the non-solicitation means if the press talks to you about something your company does, you can't say anything about it (That's why a lot of times you hear people say "no comment" when they're asked about sensitive stuff). If you have to say something at all, the company will expect you to be vague so as not to give too much away ("yeah, we're working on so and so, and that's all I can say for now").

If you say no, chances are they won't bother calling you about the job.

Jam it back in, in the dark.
