Vantaggi
The junior staff (AAEs through SAEs) are generally just awesome people. Everyone is young, funny and fun. Dog-friendly offices help to alleviate stress and the roof is amazing for sunny days. Really cool clients with a broad range of consumer and tech. Both SF and NY offices (though NY is quite small).
Svantaggi
The culture at SG is best described as that of a "kick the dog" mentality. Directors, VPs, the President and the CEO do not think twice before sending mean, condescending and intimidating e-mails -- often putting people on blast over the team alias. There's little respect for interns (I'd actually seen management address an email to "INTERN" versus using their real name) and everyone is in general overworked and unhappy. The company has the craziest turnover rate -- basically at every agency meeting, someone else has jumped ship. This company has the potential to be an awesome agency, but management really needs to get their act together and recognize that happy employees = better work.
