Okay after months of searching online for positions, today I realized that it depends on how you search for the positions.
Okay normally you would select "RN" or whatever position you are looking for specifically. Then "Full time" and so on. So the system could filter out the results and you won't be scrolling down forever.
But now you may have to select "All positions" or "All areas" instead of specifically selecting a title.
Reason being is because the system may filter out the exact postings you are looking for (for some odd reason) in turn making you miss out on potential postings that you may be qualified for.
I may be late on this but I just thought I would share this revelation. We need all the help we can get in this hard job market.
Good luck on your search!
