Avantages
Strong camaraderie among the line staff--bright, energetic people working hard until they are fired or let go.
Inconvénients
Staff, in particular senior executives, leave very quickly. There is a revolving door because the company has significant issues with paying staff and instructors. Pay very close attention to the dates and language of any positive reviews online. The company hires people to post fake, positive reviews to bury BBB or ripoff report issues and the like. Go to the second and third page of reviews because after incidents occur, the company tries to bury them with a number postings by employees. A quick search on Linked In will identify the systemic turnover problems and how former employees go on to great positions.
