Best thing you can do to get the job you want is scout what's available and ensure you're making contacts and following up. Employers know that having an experienced red team member just fall into their lap is not going to happen, so they're willing to let you develop your skills, provided you have something to start with and a drive to improve them. Certifications... quite frankly I thought they were just BS for ppl to hang on the wall and brag about, but the reality is that they are what employers consider when hiring. You can have experience at pen-testing, building networks, coding, etc., yet without any type of certification, the potential employer sees you as a stagnant product not willing to improve or grow. Almost every IA job requires a Security+ cert, or equivalent, then there is the CISSP, but you're required to have a certain amount of experience for that. I see a lot of kids want the CEH, but while it's something cool to have, I have yet to see an employer looking for that qualification.
The cert just gets you in the door, then you better be able to back it up at the interview. Be confident, but not cocky or disrespectful. Let them know the skills you have and where you want to take them, but if you're interviewing for a Web Design job, don't brag about your l33t hax0r skills or ability to break systems. Lastly, know some info about the company you want to work for. Impress them with your research and willingness to go above and beyond. I've seen people with little to no skill get hired simply because they gave a good interview... it was amazing just how little they knew too. Finally, just because you got the job doesn't mean you can be lazy. I fired quite a few college hires that started out good but got cocky (pissed people off) or lazy (never wanted to put any effort into projects assigned to them). The guy that took my university position when I moved was/is a total slacker. He's pretty much just warming the chair until the guy who hired him moves along and then he'll have no cover.
Anyway, don't tldr this. Most of it should be common sense and the rest will get you a job. Be confident, don't be complacent, and never stop learning. Good luck!
