Actually I liked talking to guys that flew for many airlines. They usually had lots of good stories and were far from arrogant. As a matter of fact I can't think of a single person that fits this profile that was arrogant at all. Almost without exception experience breeds humbleness.

Arrogance usually comes from ignorance.

Hire the experienced pilots first. There are way too many out there to even consider hiring a 300 hour boy wonder.
