I suppose it depends on a number of factors.
1. Very often the people interviewing will probably not really know what these certificates mean (this works both ways, they ignore them out of lack of knowledge or consider them irrelevant or even though they have no idea what they mean, will accept the more bits of paper you show as being you seem to have the knowledge we need).
My point is, having these does not mean you are any good (seen this too often) however, any training is a good thing, so proof of training and exposure is always a good thing. Most companies nowadays want a degree as a minimum level, to be honest this does not mean you are good, it means you are good at passing exams etc. Do not get me wrong, education is paramount be it simple following the old timer as an apprentice or spending a few years at university. Give me the old timer & University a good combination.
But there are many out there who have the minimum qualifications but can do a good job.
