Good luck in your interview!
Sorry nope, never worked for NCL, only Princess & Prestige Cruises.
To be honest the questions they asked were more geared towards personality & customer service based rather than technical. You will usually be interview by a HR person so they don't really have any technical knowledge to refer to.
Sometime a 'tech guy' might be in on the interview as well, but to be honest they never 'tested' me as such - just asked general questions such as what operating systems / applications / backup programs etc etc you are familiar with.. thats about it!
