HP Certification

I just missed interviewing for a position since I don't have any HP certifications...does anyone have any experience with them or information on their relative value. They weren't willing to consider someone who did not have them already. Honestly, except for the specific position, I don't think they would be a HUGE benefit, but by having more vendor-specific ones, does anyone think that that might enable me to look more well-rounded? I also suspect, without any real knowledge, that that they might be relatively easy compares to other certifications. Can someone dispel my ignorance, please?

Is not easy or cheap to get(or it wasn't before, not sure now). I worked for HP directly supporting HP proliant product line and HPUX tha was back in 2005-2006. I took all the courses for free @HP to get the HP ASE server integrator, server solutions and i don't recall the other names but never sat for the exams.
