Vantaggi
None, except job is easy because they don't let you do anything. In T-mobile, if you are a new comer then be expect to give no responsibility for awhile because you are invariably taking over someone else's responsibility before and they are not willing to let it go. This makes work easy becasue you're not asigned of anything in consequence anyhow. There are rampant jealousy around from the management team that has been there for 5+ years as these crowd are the least capable crowd but held the most management/athourity power in the company. Make every new comers life easy as there is plenty to do but no one is let you doing it, so just relex and lay back.
Svantaggi
Everything, they have great executive team but the VPs and Diredtors whom has been around for 5+ years are old school. These folks refuse to change, can not innovate and are so insucured they often use new hires as their blame rod. See above, the downside ofcourse, is theese crowd invariably blame all the failure on you and since you're new, they'll just have to get rid of you on the blaming game. That's why it seems like they are always hiring, they just need to hire the next fall guy in their linne up so failure can be blamed on the next new hire.
