Watch out for what you ask for. Plenty of big vendors have certification programs. ... And for some combinations of field and vendor, they are red flags - rather than pre-validation. That is, far too many applicants have the certification but do not have the grounding knowledge without which the certification is sort of useless - potentially more dangerous than validating.
That's exactly what I mean though, agree on something that actually means something. Not certs that are just a checkbox and you still get grilled bc many people don't believe they much value or others believe are a negative signal.
Develop something that actually has weight to it.
