Pros
You can work from home or at a site, if you work from site you get free snacks.
Cons
I started about 18 months ago and have made it to SSC3. During this time I have seen the company go from reasonable if a little bit "Kool-Aid" like to downright unreasonable and if you don't drink the Kool Aid they are probably going to kick you out. Every change in the last few months specifically has been driven to cut costs while maintaining the illusion of still helping customers. I have specifically spoken out about these changes and had level 3 management speak to me about how it is all about business needs. There have also been several less than great changes to the consultants that increase workload, decreases downtime, and in general, just pinching out every ounce we have to give. Other departments may have better times but this is the WORST time to be an SSC of any level, and I am looking for other employment.
