hi Skyseeker95, I know for sure SO position isn't available for the public last when it was at 2014 as you stated, now you have to be a Qatari national or have parents working with QatarAirways, and last option is MPL (multi-pilot licence) in partnership with QatarAirways provided by CTC Aviation I believe ur employment is guaranteed since I know one person from the UK got his job when he finished his training with CTC Aviation.
wish you a good luck mate, and if you have any question I will be here .
