Startup Idea : reliable resume app

Searching for a job is not an easy task those days - especially for recent graduates. Companies which choose applicants for their first job interviews rely mainly on their resume, contacts, linkedin profiles etc. The whole process is expensive, inefficient, semi-random and most important questionable in reliability.Imagine a service which do that automatically for you as an employer. It gathers (depends the filed of expertise) the right information with the assistant of the applicant and creates a reliable cv document. For example if an applicant is searching for a programming position then one of the things the app would do is examine his stackoverflaw traffic points, github contributions etc. This app would also suggest applicants how to write resume, give tips both to employers and applicants etc..
