Dejvu... I think you need to RELAAAAAAX!
Emirates selected YOU because you match their entry criteria. They are not there to kick you out of the room. It is true, I heard sometime they only select candidates by gender but if it was the case this time, they wouldn't have invited you just for the sake of wasting your/their time.
I participated myself 6 months ago to a selection process in Sydney (I wasn't invited, I just turned up and asked to be considered). I didn't make it to stage two... might be because I am married but I'm still not sure. The interview is quite nice. Usually 2 people are in charge: 1 person speaking, the other taking notes and going through CVs with a marker pen. What worried them the most during the interview, was to find out who would be ready to relocate to Dubai without problems (culture wise I guess) and who would not make it. They explained to us a bit about the company, got us to watch a video about Dubai and the daily routine as flight crew, then questions time. After that, we had to separte in to groups and sit down in circle. The topic was "how is it to live in Dubai?". They stay around the group and take notes on how you speak and interact.
During the break, they consulted each other and then called the people they wanted to stay. At this stage I was out but as far as I know, the afternoon is panel interview. I guess around 30 minutes per candidate (which is quite usual for airline interviews).
I don't know about the questions but I am sure it's the classic style regarding customer service bla bla bla...
As you can see there are many things to be done before you complete your panel interview. I really hope they'll just love you and that you get the job, but I also believe you need to be relaxed and "fresh" when you turn up. Giving the PERFECT answer to ONE question regarding your customer service will not be significant. Being yourself, remaining positive, showing your friendly and approachable personality is your BEST ASSET. If then you have a strong customer service through years of experience, well good! But if you don't, or you still need some experience before MASTERING THE SKILL of customer service, then oh well! You'll learn with time... (I don't know how old you are but I imagine you are quite young, just an idea)...and guess what? They know that!
My tip: go for a swim, to the movies, smile to people around you and do things that make you happy! This is MY way of turning up HAPPY AND FLUFFY to interviews! It might work for you as well!
Good luck!!!...
