Sorry for the late reply. But wife had the test on Nov 14th and 3 days later, the status changed to DM.
The interview was a bit of rough road though. Interviewer was cribbing about a missed same day trip. She absolutely had no knowledge about Verification of Status document can be used as replacement for lost COPR/Landing Document. So Wifey had a tough time convincing her about the same.
All in all, interview experience was just okay and that made us worry about the overall status. We are happy that its DM now and all is good.
Waiting for Oath Date which we dont need it for atleast a month considering vacation we have that is to outside of Canada.
Good Luck all with the rest of your process
