xigris,
i haven't interviewed yet, but i've got several friends who have and i'm told that the interview committee 'tailors' your interview to fit your back ground, ie. if you're a cardiac icu nurse they are not going to ask you a bunch of neuro questions, etc. i'm also under the impression that you need to know you're abg's. EVERYONE i've spoken with has gotten a question about abg's and how to correct them. i myself have been reviewing by studying for the CCRN as well (which from what i understand is a BIG plus). where are you wanting to do your clinicals, if i may ask? also, how long after you submitted your application did it take to hear you got an interview ? i myself have applied to TWU and am anxiously awaiting that letter !!! hopefully we'll be classmates come this time next year !!! best of luck to ya.
