I think the parent comment meant "self-identifies" as "your only qualification for this job is an MBA", not that you would hide having an MBA. If you wrote software for 15 years and applied for a job in tech, I would imagine the software experience was on your resume alongside the MBA -- you're not just an MBA who wants to get into tech because tech is hot but with no prior industry exposure, someone who could equally likely go be a VP of Paper Product Distribution at a Midwest conglomerate.
