There’s generally two types of positions advertised. The first is what most will look for, they’re low hour cadet positions like Ryanair.
The other, for example, is like BA who require a certain number of hours (1000hrs as an example) and often on aircraft over a certain weight. BA have their own cadet programme so they would rather take new pilots from there or hire more experienced pilots from other airlines etc.
You should search for low hour pilot jobs and see what they require, then compare that to what your training gets you. Being realistic, nobody is going to finish their training and walk into their local flag carrier unless they’re on a tagged scheme.
