I will agree that after the first interview I feel like showing your actual desire to work at Cathay and possibly live in Hong Kong is huge, if not 50% of the interview. I was very positive about the company and the expat experience. My tech interview wasn't perfect, but I still got invited to HK in November.
On a lighter note, this is going to worth the trip regardless of whether or not I get the job. Has anyone else seen the hotel we will be staying in? Beats the hell out of the Holiday Inn Express and La Quintas I'm staying in now
