Hi papillonbleu22
I went through mine on Monday and it wasn't too bad! My only non-confidential tip would be to slow things down and don't talk too fast. Its OK if you don't fit in everything you wanted to say, because the subjects are so broad anyways. The time pressure is definitely present, but don't let it take away from what you would like to say by making you feel flustered or pressured. Also, be sure to talk to the current students after the interviews because they have a lot of insightful things to say about attending UofO!
However, take that advise with a grain of salt because I have absolutely no idea how well I did!
Good luck
