Coming from a Professional in the field, I do believe now a days, certs are not as important in Tech fields, unless you are part of a large consulting team. I have no certs, no classes, but I have enouogh knowledge from experience that I can get my certs without problems, but I don't want to pay the $150 to $2k for the classes to then pay the same amount for the tests.
Good luck in your interview, and a word of advice. Don't be nervous, be yourself and make sure you let them know you are a people person... only if you really are.
