Role positioning for Talent Acquisition

This is a Microsoft Teams engineering and administration role. Candidates whose experience is primarily Exchange, general desktop support or basic Microsoft 365 administration are unlikely to have the required depth. Talent Acquisition should prioritise candidates with demonstrated enterprise Teams administration, Teams Phone or unified communications engineering, PowerShell automation and complex production troubleshooting experience.ical stakehold
