Do you have any sources that describe the asking for social media access in job applications? As a software engineer I am very lucky with the amount of jobs that is available to me, so if I were asked this I would walk out of the interview immediately. My only fear is for all those people who don't have a choice because they are part of a pool of hundreds of applications (psychology graduates for example, at least here in the Netherlands). Some employers just want to squeeze every last drop of dignity out of their employees, it is disgusting.
