Emirates had their preliminary round of interview done by agent - SAAS Atlantic. They will held walk-in interview, if u are selected, then you are qualified to go for Round 1 Interview by Emirates. Those Interviewer fly from Dubai to KL. Normally 2 of them.

Preliminary Round:
Group discussion- 10 ppl in a group, a topic will be given , and are given 10 minutes to discuss, and to come out with a conclusion. Interviewer will go round and observe everyone during discussion. There is no right or wrong answer, they just want to see how you present yourself, how you behave when there is an conflict of ideas etc.
If you are selected in this round, then you will be invited for Round 1 interview.
Round 1 will have the same group discussion also, if you are selected , then english test, then 1 to 1 interview i guess (coz the furthest that i had been thru is till the group discussion in round 1 only...)
