BTW, to all you ITT tech wannbe's.

Here's some insight on the IT side of this trade school. You may have seen my last posts further upthread. I just got a job as an Information Security Manager at a major university. Wanna know what got me the job?

No, it wasnt my master's degree from an accredited school (I wouldnt be caught dead at ITT or any other non accredited school). It wasnt my Bachelors from another private accredited school. It wasnt my 20 years as an Army IT soldier. Know what got me the interview? It was my recently gotten CISSP. Yes, my certification. I have several certs, to include NET+, SEC+, MCSE, and MCSA. If you dont know what these certifications are and you are a senior or Junior at ITT tech, you are way behind the ball. Look them up, I'm not going to do your job for you. You go to ITT right? You are smart, right? And you knew all this, right? I mean, you arent stupid enough to think that an ITT degree is the only thing you need to get that coveted IT job everyone else is going after, even those from better schools are going after, even those with certifications much better than ITT are going after, right?

You better get a clue. I'm only telling you the truth. For anyone thinking about coming into the IT field. GET CERTIFICATIONS FIRST. They will carry you alot farther than an over-rated education from a trade school and will cost you a whole lot less. The entry level IT market is SATURATED and everyone changing careers.
