That's pretty much what I'm getting at.
On the software side you're probably competing with recent grads with 2 or 3 years of academic projects (normally shyt, but its something) and possibly internship experience. So coming from nothing, that portfolio is everything. Companies will be screening on education so that will knock you out of the running for a lot. When you do get through, now your body of work has to shine enough to get you some play - that's the hard part. So if you wanted to go this route, just know it's rough getting your foot in the door. Dude I know that graduated had to go work for Target because he couldn't find anything. He also bombed the interview I set him up with
but that's neither here nor there.
IT (read as positions looking for certs) should be comparatively easier to get into at the entry level. Once you start talking the higher levels though, just having the cert isn't enough. Hands on experience is needed.
