With male applicants vastly outnumbering female ones for pilot jobs, it is much more likely that a suitable female will find herself employed as the company can easily knock back 90% of male applicants but cannot knock back female ones at the same rate or they wouldn't have any women pilots.
An operator with a 100% male pilot group which had female pilots apply but had rejected them could face accusations of discrimination, and they know this, hence the acceptance rate for female applicants will be much higher than for males as they need to be represented in the workforce.
Better still, be an openly gay female from an ethnic minority, speaking English as a second language and have a disability. It ticks more boxes than an aeronautical engineering degree and experience as a military test pilot.
