I'm considering taking DSS exams for CATIA and then I noticed the exams for ENOVIA and DELMIA....and Composites Specialist.

My question is this: Of all the exams in the image below, what would be of most value to an employer?
I'm guessing that ENOVIA and DELMIA exams are niche skills compared to CATIA Part Design, Surface, and Assembly exams.....is this correct?


Thanks for any feedback....and hopes for a great weekend to all.
