I doubt that this is an automated response, but I got a rather interesting reply from Flight Crew Recruitment nearly 2 months ago (I only just realized how it could help) :
"Please be advised that your application is still on our list of applications to be processed. Your application will be screened and considered along with all other eligible applicants in your geographic area when we next select for any future interviews.
Therefore, it takes longer time for us to process your application and all other applications of eligible applicants in different geographic areas."
Hope this answers a lot of peoples questions about an invitation for an interview. It means what it actually means. The only thing to find out is a pattern (if there's one) of how Cathay chooses geographical areas. If anyone has any info, your help is appreciated
