Vantaggi
Lots of training and support. I at least worked with very knowledgeable people. Good advancement - promotes from within. Good working environment and benefits.
Svantaggi
Big company so sometimes you can feel like you don't count. Pike was a major con, unethically telling mgmt to drop evaluation ratings to save money (this was confirmed by two higher ups), but he is gone! Company does sugar coat when they take away a benefit, like taking away employee appreciation day saying that employees asked instead of the company spending money on them that they use a day "off" to do volunteer work. Let's call an apple an apple - the company does not lose any money, gets a tax benefit from this, and for the employee is it really a day "off" since I have to catch up on all the work I missed the next day at work?! But a lot of companies sugar coat like this.
