An administrative background & knowledge of Outlook is a plus. If you work at a current company ask the staffing team if you could help with scheduling even if it's just a small amount of scheduling atleast that way you understand how to schedule.
Once you do it once, it's pretty easy, but just a lot of juggling and coordinating. Think of it like this. When you make an appt. say for the CEO and a VP you would add them both to outlook and also reserve a conference room right.
Well, scheduling interviews is similar, but it involves you pulling up every team members schedule and coordinating time slots from begenning to end and booking a conference room all through outlook.
