Avantages
Company works hard to live by thier mission statement and commitment to customers and employees alike. Although every company experiences attrition at all levels I don't think you'll find a company with such a high percentage of long-time (5+ years) employees. There are opportuniites for leadership training on a regular basis, you only need to keep alert for sign-ups and follow-through if this is the path you would like to take.
Inconvénients
Direct compensation seems to be lacking and for a technology company the equipment and tools are stuck a few years behind the power curve. They do make up for this with a strong benefits package, but sometimes the numbers on the W-2 speak the loudest. Support teams have become fragmented and isolated. The sales force seems to be favored and more motivated. Nobody wants to pay for support, but without a well managed and compensated support team users would give up and quit using the software.
