Guess what? There are no 5 day a week - 8 hour a days positions on a ship
Most of the jobs are 7 days a week, and you might get the occasional evenings or afternoons free . . . and this is everyone from the bosuns 'swabbing the deck' to the captian!
The T&D job . . . you'd always be on duty turnaround day, processing departing and new crew members, then the same day and next for 'new joiner' training sessions, then the rest of the cruise for the ever present and on-going staff and crew trainings.
It's a good status job - meaning a 3 stripe officer on par with the cruise director, F&B manger, Bar Manger, etc and most of the management staff. Your own cabin with a porthole, dining and bar privileges most staff/crew don't have. Three-stripes comes with added responsiblities, like being part of the weekly ship inspection team, or on rotation for night duty manager.
Salary range is probably about 25% less than the HR Manager
Nice thing about anything 2 1/2 stripe and above positions is that it's paind 4/2, which means for every four months you work, you're paid 2 months salary when you end your contract, so in theory, paid year around
(assuming you're interviewing for the same company as the HR manager listing?)
good luck and let us know how you do!
