Last year one of my friend’s friend(a guy he was friends with bc they studied for ielts together) got a call from vo and they interviewed him. I don’t know about the specifics but yeah it’s not nonexistent! Just like I said it’s extremely rare but you can’t just rule it out bc no one here or none of your friends got an interview call. This forum is just a tiny fraction of international students who want to go to Canada, most of the people that I know don’t even know about it or even care to join this forum. Take the instance of rejection, almost none of my friends got a rejection for study permit but when I come here and see all these threads about rejection I get paranoid. Same is the case with interview, there might be some students out there who have had interviews and have not shared about their experience on such forum.
It’s still extremely rare but judging by the scenario atm I don’t think anyone would be getting a call for interview as there is a huge backlog of visa applications lol it’s either accept or reject
