What surprises me the most is how a corporation like Google is incapable of meeting temporary staffing needs internally, by shifting people already on their payroll around projects. It's as if they are just admitting that they are shit at managing projects and workloads and scoping work to the point that they need external help to plug these gaping holes in their load management.

How many people do they need to pay to manage this contractor circus? How much effort do they waste sourcing contractors, tracking work assigned to them, treat contractors differently even interns of security processes, and dealing with higher attrition levels? So much waste.
