Qatar Airways or Emirates?

All airlines are hard to get into - most follow a very similar process and it is more about finding the right airline for you. It's not like applying for any other job and it usually takes time to find the right airline, you may be perfect for Qatar but not for Emirates, for example. Each airline has their own strict guidelines for recruiting too and the recruiters know exactly the right kind of people they are looking for that also meet the requirements and image of the airline...

It depends. As mentioned, most airlines follow the same process. But if you’re comparing EK and QR, i think it’s actually harder to get a CC job with Emirates since it’s more popular and the competiton at OD or AD is bigger

Hardest in my opinion is Etihad, less cabin crew = they hire less and less open days. (was previously a 5 star airline)
6300 cabin crew

Second hardest is Qatar. Added requirements to application + less open days/ assesment days. They scrutinize your application to the slightest birth mark/scar.
Qr has high standards(discipline) 5 star airline
13000+ cabin crew

Easiest in my opinion is Emirates. They hire loads of people, they prefer inexperienced applicants and they hold 100+ open days/assesment days per month. Ek is more casual
23000+ cabin crew

Nonetheless all are good airlines and all have their pros and cons when working with either of them.
