MissSmith & PB138,
I believe this is a EK Cabin Crew forum. Answers to all your questions and more details about the recruitment process with Emirates can be found at:
EMIRATES - Wannabees & Recruitment I and
EMIRATES - Wannabees & Recruitment II. Those forums have plenty of valuable information. My suggestion is to go thru every single message posted and you will do just fine during the OD you are planning to attend.
Also, keep in mind that your first resource must be the EK careers website, read it carefully.
www.emiratescareers.com
Good Luck.
