Agreed. This Darren person might not always remain at Ryanair... It's not just a stepping stone for pilots I imagine. Doesn't matter how low you believe the chances to be, you will see that when you apply for a job at a place you really want to be at and you are qualified etc, you will get a friendly reply from someone named Darren telling you to sod off
I actually know a few cases like this, including one where someone who felt improperly treated by my old flight school ended up in HR for a major airline and pretty much any CV passing before his eyes that listed that specific flying school went straight into the bin.
