When I applied I got the same automated email, and since it said a lack of reply was disinterest in the country, I too replied. No idea if I needed to or not but about two weeks later I got a call for a interview that was maybe a week after that. Could be the reason why they're not calling back as fast is, they were running two 20 people classes a month and now they're running one 16 person class a month because they were having trouble finding enough sim time for the initials and all the captain upgrades we've got going on. No idea if it'll go back to the big classes after most of the upgrades are thru.
