A degree is NOT a requirement, and like any company the goal posts move according to their perceived future requirements. The recruitment process is comprehensive with a computerised technical exam, crm exercise,fixed base sim ride (in the Hawker Pilot Trainer), personality interview etc. As they do not have a bond or pay for type rating system the emphasis, beyond flying ability, is on finding people who will stay in Perth and who will be at home in the Skywest family. Despite that, both Cathay and QF seem to really like poaching from XR.
