Previously, when pilots (or even people who knew what an airplane looked like) were involved in recruitment of pilots, it would have been advantageous to interact with these recruiters at the flying school used by Cathay. Several current pilots did just that and it led to them getting jobs.
As others have pointed out, Cathay recruitment is now done by clueless HR robots so it would be a much better idea to just get a license that is recognised in HK at a location, instructional standard, and price that you are happy with.
