I endorse Jarse's comments. I hope I don't have to sit beside your friend on a professional basis as he seems to lack integrity.
Then there's the story of the bloke who similarly lacked integrity WRT supposed qualifications and managed to get a job at AN some years ago.
Not only did he lack integrity but was too stupid to know that one shouldn't brag about conning the employer. I don't think he made it out of ground school!
