Avantages
The company gives you time and money to study and they give you complete control over how that is used. Conferences is the obvious choice, but I took time off to learn a new language that was not used on any project because I was interested in it. They ask, but don't require that you share the knowledge with others in the company, maintaining a good knowledge of who is the person to talk. Cyrus believes in having a good life outside of work as well and try to make your personal life better because of the benefits that Cyrus provides.
Inconvénients
Most of the problems are inherent in consultancies. The clients have a problem, that's why they bring in outside help, but want to improve. You are given a say in which client(s) you work with, but it's just one part in the decision of where you are placed.
