Good time to queue for that cabin crew job

From September 2015 till January 2016 a period of 5 months SIA has or is going to conduct a total of 7 cabin crew interviews ( 2 in Sep & Oct in JKT, 2 in S'pore, 1 in KUL, 1 TYO, 1 in BJS).
SIA is in desperate need of cabin crew. They need at least around another 700 crew (my guess) for their expansion and replacement of those who had left.
I would encourage those who have failed previously to try again unless you lack the minimum educational qualification or failed to meet the height requirement or have skin problem or too "old" (guess 30 is the age limit) or have criminal record or in the "blacklisted" category etc.
You do not have to attend my "Talks" to make it. As long as you are suitably qualified you stand a reasonably good chance.
The queue this time may not be too long as in the past due to the reluctance of some who are afraid to fly because of security concern (downing of MH 17, Russian Airlines in Egypt and the terrorist attacks in Paris, Istanbul etc).
But to the cabin crew wannabe diehards, this is a good time to queue up for that dream job.
