What Grant says in answer to that is good and useful. But he forgot to say that even if he respected the certifications at a lower level than MCM all they would do is help you get the interview, they would not be an interview topic.

In your CV (resumé if prefer to you call it that) tell us what you have done - you are someone with a good knowledge of X industry who has learnt database stuff in order to do things for X industry, and you think what you have learnt maybe has a wider scope - so tell us what you have learnt and what you are doing to contuinue learming, tell us why and how the X industry reports you produced were valuable to your employer, and tell us why and how you think your knowledge and experience could be valuable to us; if you make a plausible job of that, we'll move on from there - maybe a short telephone interview to se if the CV appears to be real, not a fabrication of lies and hald-truths; then a face to face interview and don't be surprised if someone like me brings an X-industry expert to help me at the interview. Technical questions about the database things you claim to know; questions about whether you've taken studying database stuff further than you nedeed just for the job you were doing (if you have, and can discuss the stuff intelligently, that's a big plus; but I won't expect you to demonstrate competence in things you've learnt but as yet have no real experience of). Expect questions that are about attitude to work and to colleagues, too - I will need to know if you will fit in: someone who can't fit in with the team is no use to me, even if they are a genius. And expect questions about your willingness to learn and to take on responsibility: someone who won't learn would be no use to me, and I'm not rare in that respect; someone who isn't prepared to take responsibility for anything may be employable in very junior posts, but in any other post only if I have a vacancy where it doesn't really matter if that job gets done (regrettably, company bureaucracies sometimes generate such jobs) and normally I don't tolerate the existence of such posts.
