I was unsucessful my first time, interviewing for SO. Got past the first interview in YYZ but not HKG.
Years later I was invited back for another chance, this time for DEFO. But I turned them down, had a better job already. Funny how your perspective changes.
They didn't even reply to my correspondence declining the interview. Classy. Although I suppose it helped to affirm my decision!
doubleu-anker is correct...I would move on. Cathay is a good job, but not so exceptional anymore you should get tunnel vision. Tremendous amounts of opportunity at the moment worldwide and if you are competitive enough to be considered at Cathay you certainly don't have to settle for pursuing only Cathay.
