Pros
I have worked at Ascendant for some time. I have a good relationship with many people including upper management. Consulting is a lifestyle decision. Many people want to be a consultant without having to travel which generally isn't possible unless the client is flexible. Sometimes I will be away from home for 3 weeks straight, sometimes I will be at home for 3 months straight. Sometimes I will be at a client for 3 days, sometimes I will be at a client for a year. It all varies as is the nature of consulting work. If you work hard, contribute, and help other consultants become better you will be recognized and rewarded.
Cons
Everything was mostly perfect until the Avnet acquisition. There is a lot more bureaucracy and annoying 'busy work' that you have to squeeze into your personal time. There have been a lot of organization changes and many great people have left.
