I honestly believe it is nothing more than showing you can play well with others. It is a problem that is timed. They know we will do everything to solve the problem before the time, so it is a diversion. Be involved, don't dominate, don't overwelm.
Since they are timed, the first thing to do is jump right in and say something along the line of "Bill, you have a great big watch, why don't you keep the time."
I believe it is all about showing you can work as a team.
