I worked at a company that did this. This company always pair programmed. So the interview took place at a pairing station. We gave the candidate a choice of about 10 toy problems to solve, and then we coded for 2 hours. They could use Google, their preferred IDE, whatever they wanted. Of all the companies I have worked at, this was by far my favorite interviewing technique. But, I think it works best when you pair with the candidate. So if pairing at your company is not done, it might not be a good fit.
