I was once privy to a CV from an engineer who claimed he was a "Director Designate " for ABC no less....alas.
Unfortunately, for him, his rapid departure from the UK and equally rapid departure from his then M.E bolt hole was well known, as was his capacity "to be economical with the truth "....along with a certain lack of attention to details when it came to the dates and content of his "impressive qualifications " as glowingly provided on his CV.
Used to meet, in passing, a genuine ABC engineer quite often however. This was in the 80's / 90's, an elderly guy with a beard is the best description I can give, but always a nice guy and always working alone. Which mustn't have been much fun on the then elderly Merchantman
