If you do "lie" be VERY careful as anyone with any interview experience or even just good people-reading skills will ask a follow-up that will trip you up.
You have to ask if the risk of that is worth the risk of NOT getting the job
'cos if you DO get caught in a "white lie" nobody would employ you.
"mild exageration" is possibly OK, but even then it can trip you up. The person who says they "led a team doign X" will get asked about the steps taken and ONE slip up showing they didnt' "lead" means the door
IF you fill in LOTS of application forms, spend 4-6 hours writing and honing a CV then you have a CHANCE that exagerated-facts won't be spotted. BUT you really need someone to do mock interviews to test your skills at maintaining the "lie". By then you've created enough "image" for it to stand up to noddy-interview investigations.
BUT I have to advise that if you can't get a job by the "truth" ( even if mildly distorted" then why should you deserve a job by lying ? And woudl you enjoy it, stick to it ?? It's a classic short-term solution which just gives long-term problems.
'course if the job is a part-time stacking shelves type then it's not that important what you say to get it ( except as advised do NOT mention Puff
)
Good luck whichever way you want to take it.
