I'd like to know how that "friendly and happy" translates into educational. Does the company develop you into the fine teacher you are to be? Or, do you teach the company/students how to use the language they want to learn? I wonder whether this company serves as a third party that sends you to places of their choice and whether it arranges a work permit for you too. The reason why I am asking is that there are scores of "companies" that act as if they were escort services with people who travel from far away under the assumption to teach English in a legal school which provides them with a legal work permit.
