It's pretty common for developer positions regardless of where you live (at least in the United States). When I was on the east coast and when I moved to the west coast, every single interview consisted of hours and hours and hours of whiteboarding. Some of the better companies had you whiteboard something you'll run into on a normal basis (like drawing up how you'd architect a RESTful API). But most of them was "here is this CS problem that you'll either never have to deal with on the job or can look up in 2 seconds because it'll be easy to recognize; now whiteboard it up with zero help from the internet".
