What I would really like to see is for employers to give actual feedback to the rejected candidates at any stage of the interview process. I am sure that employers can find a way to share constructive feedback without the fear of any legal implications. And I am sure most candidates will really appreciate a meaningful feedback instead of an automated rejection email. This would also have the side effect of having only serious candidates and employers engage in the process and should go a long way of getting rid of these ghost jobs. I would love to see a job board which only post jobs where the employers promises to share a feedback with any candidate they interview. I am sure it will be a hit.
