wow, that's exciting but nerve-racking! im quite the same, i left mandatory education about a year ago, and i didn't decide to go to university yet (well, i did but quickly left for mental health reasons) and now i've not been employed yet ever properly. so i would definitely be the same. best of luck with getting the job, and also good luck for going through with it, im sure you'll be excellent! do you know what type of job you're likely to be doing? :D
