they also ask you how often did you communicate with each other?, do you have any relatives in Canada?.
It is one on one interview, just like a bank.. you know the typical bank cashier has cash. she is on other side, you are on other side counter with the chair. be confident with all your answer, if you don't understand the questions ask a question again. give your best answer for each questions, they just wanted to see whether this marriage is legit or not.
In some cases when Vo's thinks that we need to have an interview if they feel something suspicious or they might have questions about your marriage. they have right to call you for an interview.
It is not mandatory that your spouse needs to be there with you, if they have any question VO's can phoned your spouse. so tell your spouse to be online on phone, or took a day off for 2-3 days and make sure you both communicate with each other with all the answers, your answer needs to be same..
