Guys and girls, I am really surprised you are so disappointed to not get a call from them for an interview. I'd imagine they pick names out of a hat more or less. There is absolutely no strategy. I nigh on guarantee that in the long term (and quite possibly in the short term if you did but know it) you will be better off for having not been 'invited' for an interview. There is only one person making Ryanair 'the only way'. I know of more than a few people who wish they had never done the selection, some of which who passed. There also seemed to be no consistency in their pass/fail grade there. Get another job (non flying almost certainly) and sit the recession out, I've said it before and I'll say it again, our careers are a marathon and not a sprint. And I am not saying this as a bitter person who was not 'selected' or who failed I can assure you.
Good luck and get long term in your goals.
