Haven't been here for a while but here goes.....
I went for an interview recently at CTC and passed both day 1 and 2(sim). It wasn't like any airline interview I had been to before - not that I have been to that many. I followed the tips left on this thread by others who have gone before me and it worked. So, woohoo. I will be going for a final interview soon and it all seems pretty cool.
I must say that I found the process thus far to be well organised and professional. Easy to have a positive perspective when it works out but for what it's worth it Sao far looks very good indeed.
Good luck to the guys going for the interviews. Study this thread thoroughly and you'll get an accurate idea of what the whole process is about.
