Well, one of the first thing you will do before the test is to promise not to share any of the questions to other applicants. But if you have read the guide book and googled Canadian Immigration Test Questions you will have a pretty good idea of what the questions will be.
As for the interview, I think it is different for everyone (interview was done before the test). For me it was a lot of focus on the travel I had done for work which resulted in RQ. I passed the test, but are now waiting for RQ to be reviewed.
Good luck
