I HATE LYING!
I had a guy that came to work for me, saying that he was a fully qualified engineer. It was an internal transfer. I asked for him to bring in his qualifications for me too see, on many occasions, but there was always some excuse or other.
He didnt know things that I would have expected an apprentice to know in their first week of employment, and his work was very poor quality when he did manage to get something done. LIAR LIAR

Needless to say, he was soon transferred back to production.
He also told us that he was a professional goal keeper, and had played for England! This guy is as round as a bloody football! Eh...LIAR

If he had told me that he only had some experience, I would have trained him up, but I hate a bloody liar, so he got the boot alright.
