no but some are. I have worked in consulting for a while now and a lot of the experienced hires that come to my firm are just chavs. I know one hired recently. Unshaven, smelly, bad grammar and no sense of professionalism. Uses language that should be saved for the terraces at his local football club. The analyst intake tends to attract the right sort of people to the firm. Bright, willing and wanting to learn but above they have an excellent command of the English language and great analytical minds.
