Aspiring and working data center technicians, infrastructure support candidates, and people moving toward AI infrastructure roles. The focus is practical reasoning, not a coding interview.
You can join at any level. Our planned prep covers fundamentals through role-specific scenarios. It is designed to complement hands-on experience and certifications—not replace safety training or employer procedures.
Pricing has not been finalized. We’ll share details when early access opens.
