Re: Interview in boardroom - any advice?

Excellent advice all around. Most professional cameras will let you set the game at minus 3. That will allow you to get iris open a little bit more for the depth of field.

Aside from all the technical stuff don't forget about taking care of the client
If you have time budget you may want to go over early with your camera and experiment. Be sure to have the shot completely blocked and setup before the big wigs come in. You don't want to waste anyones time.
