Justcruisin is a legit site, but then Seven Seas is also. JC is out of Canada, SS out of US. Both really ARE hiring partners for cruise lines. SS has a better reputation than JC . Even if you get thru on a RCCL/Celebrity/Azamara site, they're going to send you to one of those for screening and giving all your info to. (look at the list on RCL website link for hiring partners - you'll see both ..... http://www.royalcareersatsea.com/pag...iring_partners
and pick USA from the dropdown list)
If you're asking for one of the recruiters to get back with you - you might be waiting for a LONG time, esp if your question requires more than a simple sentence. And . . . if you haven't heard anything, give it a week and resend. Keep your name on top of the pile - they get a LOT of resumes and it doesn't hurt to be persistent.
