These days Queens is hiring mostly from the inside but even those who have already been working for years in other positions at the hospita have a tough time getting a new grad spot when they graduate.
It is definitely a "who you know" situation for new grads.
The odds of an outsider getting a new grad position are extremely slim. Queens has lots of aides, unit secretaries, techs, etc, who are in nursing school
. There are also many long-time Queens employees who have sons and daughters who are in nursing school. When these students become new grads they have an advantage over the outsiders, without a doubt.
I think the ads that are showing up briefly on the internet are just a formality and I would bet that they have been spoken for before they've been posted.
No harm in trying to apply for these positions and who knows---you might just get lucky! The odds are really bad but it can't hurt to try.
