Think "call centre" and you usually think long hours in drab cubicles. The call centre for Airbnb is nothing like that -- there are shared desks and lots of meeting areas.
One clever trick Airbnb has adopted is a "landing space": an area where employees (there are 250 at this site in Portland, Oregon) can keep personal items and charge their phones. That avoids one common hot-desking complaint: having to fight to get a good position every day. Hit the link for more about Airbnb's approach.
