Yes! HigherMe can sync with iCal, Google Calendar, Outlook, and Yahoo.
To add your calendar, simply select the Interviews tab, then select "Add to Your Calendar" on the right side of the screen.
You can add to your calendar when you have one or more interviews in your schedule under your Accepted Interviews.
Note: This is a one-way, one-time sync meaning that if a candidate reschedules the interview, or if you or the candidate cancels the interview, those changes will not reflect on your calendar. You will need to manage any changes to interviews via your own calendar.
