As a coordinator, you're in charge of organizing, planning, and executing events or activities properly. That can even include making sure the team that you lead works together efficiently and effectively.
Most coordinators earn a bachelor's degree before even considering this job and a lot of them have prior leadership experience. Either way, you need to make sure you can prove that you can lead a team to pull off an event successfully.
You'll rarely ever need to work overtime as a coordinator but you might expect some overtime during busy periods. Usually, you'll just work a normal 40-hour schedule.
