Yes! HigherMe can sync with your iCal, Google Calendar, Outlook, or Yahoo calendar application.
To add your calendar, simply select the Interviews menu, then select "Add to Your Calendar" on the right side of the screen.
Note: 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 changes to interview bookings on your chosen calendar service directly.
