I am trying to set up a service to occur on specific days at specific times for quick interviews (15 minutes in duration). For example, we have from 3:00 - 4:00 pm on March 28th, 3:30 - 4:30 on March 31st, and 1:00 - 4:30 on April 1st. I've set up the service and changed all available options for duration specific to the service (so not using a default duration) to be 15 minutes. However, when testing the booking service link that will be sent to candidates, the time options continue to show up every 30 minutes rather than every 15. For example, when I look at the calendar for March 28th, the only options are 3:00 and 3:30 rather than 3:00, 3:15, 3:30, and 3:45.
I've set up multiple other services where the timing is either 20 minutes or 30 minutes and through testing, it works just fine. Is there a reason the 15 minute duration isn't working?
