Vantaggi
On the positive side, when our small company got purchased, we did get salary increases (which was good because prior to being purchases we hadn't had any raises in two years).
Svantaggi
Even if you're currently using state-of-the-art technology, you will be converted to mid 1990's software. While they talk about 'the cloud', you quickly find out they actually don't know what that means. Be prepared to spend as much as half your day in new meetings. Suddenly your mandatory meeting is more important than actually doing your tasks. Also - they are adamant that you not 'work from home'. They want you in the office even if your other team members are located in other offices. When you get absorbed if you were working from home, you won't be any more.
