Q. What's the difference between "required" and "preferred" DC plumbing + fire suppression certs?
Required = your application is filtered out if you do not hold this. Preferred = your hourly rate jumps (typically +$5–15/hr) if you do. New applicants should always hit the required list first; experienced workers chase the preferred list next. Source: Equinix/Digital Realty operator requirements.
