Cathay is a seniority based airline....(well, pretty much anyway
)...what this means for you is this: ALL S/Os are based in Hong Kong, with the possibility of a 2 month temporary base once a year, this may or may not be in Canada, up to the companys crewing requirements. If you are successful, you will be at the very bottom of a large pile of pilots, now around 2600. Once you upgrade to FO, you will then be eligible for a permanent base, assuming you actually upgrade onto the fleet that serves your base bid, and if you are the most senior, or senior enough to hold a base position, then you will be awarded the base. However.....the bases have been filled up by the DEFOs, and so base slots are becoming very rare, so when they do come up, usually quite senior people are taking them. In a nutshell, dont come to CX or Hong Kong expecting to be here only a few years, your looking at 10 years at least before you get a base. As well, all commands are done ex Hong Kong, so its back to the Fragrant Harbour and back to the bottom of the Captains seniority list before bidding another base....
Good luck with your interview, the majority of people here in CX make it an enjoyable place to work.
