For more technical roles, breadth of experience across more than one platform is the key to being hired, the update says.

"There has been an increase in demand for skilled system administrators and engineers with broad technical strengths across multiple platforms and networks.

"Employers now look for candidates who tick a few more boxes compared to last year.

"This is a reflection on budget and cost constraints, plus the process employers now go through to get sign-off on hiring."

Data warehouse experts and database administrators remain in demand, the update notes.
