There only jealous, one of them is unemployed and the other works for Ryanair and probably envy you and your chance to work for a proper carrier. I am an SO, not with QR but some of the SO's I work with were captains at Ryanair. Don't have any info on the questions but your English is fine, my spelling is so bad it is unbelievable and really it does not matter. I just always find it funny when people comment on spelling or grammar. I expect english is not your first language as you are going for QR and list yourself as living in DXB. It probably wont be too tough and if you have prepared for the interview you should be ok. Sorry I could not be more help.
Good luck.
