Why we need to build an awesome resume before we are going to apply for a hire?

How many HR and business owner were tricked by such an awesome resume and profolio?

Resume is a MUST in almost all the interview, it may partly reflect someone's history assuming that guy is honest. Wait...how I know he is honest? Am I going to hire a resume?

We always have a myth on how to determine one's ability, resume is out in 21th century. there should be some platform to show our ability history, employer can look into it to understand our problem solving skill and even our mind set.

We can realise his standpoint or even political position, these are all the valuable information we are looking for before.
