You have to stop freaking out. You know you are made for this job. You know that shit asshole head of cabin crew office or whatever the hell his position is called in English wants people like you so bad he's willing spend hours talking to some Israeli dumb dumbs most candidates are. You aren't perfect, but you're young and willing to do a hard job and sacrifice your health and shorten your life span in exchange for some symbolic salary which rises just a bit above minimum. All that wearing some shit uniform. Other candidates may be best of the best, but they have no idea what they are applying for. You're aware it's gonna be tough, no vacations, no layovers, no days off, no fun. And yet you want it badly. You are a realist that haves it all except proper vocabulary which is no big deal for a language learner like you are. So stop freaking out, just go there and get what is rightfully yours - damn wings.
