Are these queries genuine? Most are queries on issues that with 5 minutes reading on the forum, all answers would be given in detail.
Pay, Housing, Education, Profit Sharing ???
Well try the EK recruitment site. Read the posts on Pprune. In fact read the very thread. All answers are there in graphic detail with pros and cons debated.
I suspect some of these queries are placed by managements to get recruitment threads to the top of the list and displace less savoury discussion.
There is a pattern here and not particularly opaque.
