To be totally blunt, as someone who used to assist in interviews in community pharmacy, lying in an interview is the worst possible idea. Sugar coating or emphasising certain points is totally acceptable, and being vague about a dismissal is almost expected, but to falsify information is a sackable offense.
A little trick I learned to catch out those lying about foreign language skills, is to learn one sentence from the language they claim to speak. Something like 'so how strong would you say your (language) is?' spoken in the foreign language. If they look at you with a horrified expression, chances are they exaggerated their ability. If someone lies about one thing,it implies they will be willing to lie about other things.
Deceit is not a desirable quality in an employee, nor a person.
