I just went to my interview at Vancouver today at 10 am . I came out of the building at 2:20 pm . It was almost four hour wait , in a room where there is no tv nor magazine but your own documents to look at . You're not allowed to bring cell phones or food or water with you and you need to leave your big bag outside of the building at the security check entrance . Try not to drink water cuz once the let you go up the elevator to the waiting room , there is no washroom for you to use . You'll need to leave the building and go through the check and line up again . Thus , eat something but no drink before you go . I almost fainted when close to 3 hrs waiting . the interview part was easy only took about ten minutes less than ten questions . I keep my answer very simple . I heard the guy before blah blah blah about he and his fiancée reunited after 15 years . Then the officer asked him whether they both had previous marriage and how they settle divorce and where the kid and custody .....my advice - keep answer simple and precise ! and be prepared for the extra documents . The girl before me got send back for more documents after waited for 4 hrs ...feel sorry for her . Anyway it's a long day for me ! Good luck to all
