No hes in a professional job, i can see everything on his online profile on linkedin. I dont think you can really lie on that to be honest as companies use it and you cant get away with it.
Its really not beyond beleif lots and lots of people i know have professional jobs in the finance world at very high position without a uni degree.
With this guy im not doubting his job, i just think why not finish the degree? what values does he hold about education? etc
