I was searching for a job about a year ago, and I remember it's a more-or-less difficult time... you get to be sitting at home waiting, trying to improve your CV, searching for offers, and most of all, thinking more than enough about "what you can/could do"... in reality, it´s not your decision, or your own responsability if someone picks you for an intervew/job, it's the intervewer pick. That is, don't put the responsability only in your shoulders, because it is not yours, it's of the persons that make the selection to interviews (and sometimes, as everything in this world, people just aren't perfect, and it could most probably happen, that there were a perfect job opportunity, you being the perfect candidate, but the person in charge of the selection just didn't see it...
So, meanwhile don't think too much, keep sending CVs, thinking about your future, and enjoy the available time that you still posses (shortly, when they call you and you start working, you will miss that precious time... that's unfortunately true...)
As for having NO EXPERIENCE, well that's just normal. Everyone starts from there. And with you it's happening the same. Don't worry, keep sending CVs, and you will see, that sooner or later you will be working ang gaining that experience. It's that simple.
P.S. I'm also studying for the CCNA with Sybex 5th edition. I've finished the first chapter yesterday, and I must recognize: I studied Telecommunications Engeneering, and already knew some parts, but if I didn't, I could'nt understand many concepts that were just named from a start, without introduction... Still hope it will get more clear in the next chapters...
