The probability of Interview is very low in all applications. Most of the time Interview is called if they have a doubt with your Work Experience and they would like to question you related to your field and try to find out if you can really do these type of work or not.
However, there are very few instances where applicants were called for interview to ask general questions to confirm that person is actually fit to enter Canada and is not simply getting 3rd Party help to enter Canada.
The type of questions asked in the past are as follow: Source (
