Marriott works a point system scale for all answers. There typically isnt. Wrong or right answer BUT there are strong & week answers.
Basically you will need to be as thorough as possible with your answers, stick to the point, while hitting these main categories.
1) The issue or problem.
2) what happened.
3) the actions that lead issue/problem
4)the actions you took to resolve the issue/problem
5) was it resolved.
Not all examples/answers have to be resolved. They can also be a learning experience. In which case, be sure to state what you would do next time.
Always dress the part.
Bring resume & portfolio pad, take notes!
Have at least 2 questions to ask interviewer.
Ask when you should here back. (Follow up!)
ALWAYS end the interview by asking for the job "I would love to have the oppt. to work with marriott. I look forward to growing with the company." let them kbw that if they have any further questions for you that you will be more than happy to provide them with any info they may need. Thank the interviewer.
Always, send thank you card!!! No matter what.
Good luck!
