Pros
The people doing the actual work. They will bend over backwards to make sure their clients are happy. They are helpful, intelligent, hard working.
Kontras
After the acquisition of CheetahMail, the onset of business politics took over. There have been several re-orgs and layoffs which killed morale. The best employees and talent have now left the company to become directors at their clients. It is unfortunate, because there was a time that this was one of the best places to work. Now, if you do 0 work, but spend your time buddying up with management you are guaranteed a nice position and pay. There are several people in management who are of no use, lack the merit, and definitely haven't put in the required work to be at senior leadership level.
