I've been gunning for my dream job for four months and three rounds of interviews. Today was the final step, a presentation given to 14 executives of the department.

They seemed to enjoy the presentation (about the future of tv) and asked great questions. I'm wondering how to word this final "Thank You" email tomorrow, short and sweet at this point since I've been there already? Do I "thank them" for participating? Any advice would be great. Thank you.
