Keep in mind that there are no good airlines that hire DECs. If you do come to EK you will be treated like ****e and forget about any promises or contracts they may offer. They are made to be broken.
Speaking of broken so will you be. 90 plus hours in the middle of the night and then to top it off you will have to babysit a DEC that took your job. Even longer to upgrade. Are you sure you want Emirates?
