It is the same in many areas I think. You get in if you know someone, or have a prior established rapport. At the very least that is a way more pleasant way of finding a new job.
yeah but why you have to make an official job post? and not offer the job directly? In gov they are forced by policies, but most private orgs dont need to do such gymnastics.
Depends where you are (jurisdiction)... in some countries the law requires an open offer.
