Personally, I don't really get this type of interview. For one it sounds like they've pretty much standardized it for all developers with little insight into how a new candidate might fit into an existing team best. Also, it simply does not reflect in anyway what it will be like to work there or what it will be like to work with that person. One key reason is that the interviewer asks questions they already have the answer to and that unbalances things and results in an inaccurate analysis. In real life, none of the people in the room would have the answers and they'd all be working together to solve the problem. These people come and interview all day. The team would be better off just having that person tag along with them and work on real problems together all day.
