Different departments need different backgrounds. A housekeeping applicant, chef, youth staff member, retail salesperson, technician and officer will not be assessed in the same way. That is why your CV should show experience that is relevant to the specific position rather than presenting one generic work history for every vacancy.
For first-time crew, land-based hospitality, customer service, retail, food service, cleaning, childcare, entertainment or technical experience can still be useful when it clearly matches the job. Senior and specialist positions normally require stronger evidence of experience, qualifications or licences.
