Dear WOK4CX,
Not sure what you're after as I note you already give your profile location as the New Territories. So I'll assume you are not a CX spy.
In reply, my impression of my cocktails deal (was in the old Kai Tak HKAC then)was a chance for you to meet the Mgt (usually DFO, HR Mgr etc) and for them to observe your social compatability with firstly other recruits and with their own expectations.
Often your sim checker will be there too, together with recruitment bods (TP or AL) - so theres someone familiar for U. The offical line was it was not part of the process but anyone with a little savvy could tell what was going on. Friends in the know in Flt Ops have confimed this to me.
Don't drink to excess, don't tell dirty or chinese jokes, and please make sure your wife makes a good job of acting like she loves HK and U - forever! It does not look good to have an overly ambitious partner who looks like she'll dump you at the first sign of a good job offer! (Its happened!)
It doesn't take long - just play it cool and middle of the road. Airlines don't like 'personalities' these days I'm afraid! Be bland but nice & PC and you'll be fine.
