the energy level was extremely high in my opinion there were people everywhere and in offices as well,there had to be at least 30 or more cars and company pickups -employees were working on all different stuff from computers and wiring to welding and grinding and testing stuff outside -as far as lunch ,i was eating lunch as well so i cant comment on who are or where they ate -and i also dont know about a second shift-but the overall atmosphere was energetic imo -lots of activity at all levels inside and out-moral seemed very high -hope that helps!
