Anon speaks truth.
Certs get you through HR. Many times, HR has no idea about what the position demands in a technical aspect, so they are looking through/at different resources for what is commonly asked for in other postings.
I fucking hated my time dealing with recruiters who specialized in placing technical positions, but the same stood true there...certs will cause there...
WHen you get to the actual interview with the hiring manager (and usual a couple of employees who are likely to be your coworkers), most of them are not going to give a fuck about certs 99.9% of your certs.
WHat they are going to care about is your passion for the subject matter, your experience, what projects or side projects you are/have been involved with, your current capacities, your current skillsets and the dynamic existent during the interview.
This is the most important I think: if the interview becomes an hour of the three of you shooting the shit about security (or whatever you are interviewing for) and doesn't at all feel like an interview during this, it is likely you are going to be hired.
