To host more than one 1:1 interview at the same time with different locations and moderators, you will need to add multiple slots in the calendar for the same time (see gif below).
Each slot has a unique moderator and location. If you want multiple participants to receive the same location information, you can set up your slots that way. However, if you want to be able to assign the participants to a different moderator or give each participant a unique session link or location, they will need to be in different time slots.
