When people click the link, they can schedule meetings with you at any of the times you carved out for them. Appointment slots allow you to carve out specific times of day & week on your calendar and then share these times with others via your Google calendar's appointment page link. If the above scenarios resonate with you, you definitely want to check out the Google Calendar Appointment slots. However, sharing your own private calendar raises privacy concerns, and integrating with a third party tool, such as Calendly or Hubspot adds yet another app to your already overflowing digital tools, and the maintenance experience can be cumbersome. As an advisor or mentor, setting up 'office hours' so mentees can book time with you can be extremely handy.
