Sales people doing relationship/long-term sales can build trust with customers. If you are purely transactional about it (and willing to say anything to get maximum salary) then it may work, but it also may backfire.
If your hiring manager is the one you are lying to, they will also be responsible for your raises, promotions and bonuses. It's a long term relationship, one which can last beyond the current company you are at.
It's a small world in technology, and beyond hard skills, your reputation is all you've really got.
