Out of curiosity, where did you get those numbers nairna? It seems like a logical weighting, but I would have thought your ROTP questionnaire would be more.
Keep in mind that your interviewer probably is not on the selection board (I say probably because I am making an assumption). They can only score you on the interview in the interview, and that score, from what I know, is really all that counts. If they find you suitable for the job after the interview, then thats that as far as the interview part goes. I think. I might be totally wrong on that.
But nairna is right, I wouldn't worry yourself too much. What's passed has passed. They likely would have told you right away if you were not found suitable for whichever jobs you chose. You've made it this far based on how well you've done, so don't start worrying now!!!
