Make your own assessment regarding working for whichever airline, but if you pass the interview process and get offered a job, you will at least have the opportunity of making a choice or getting a job (should that be the major issue).
Interview, assuming it's in a 777 sim at EK, will be in either the 200ER (sim still called the 200EGW - the original designation for the 200ER), Rolls Royce 300 or 300ER.
