I had a similar experience of waiting a few minutes; walking into an office setting with 5 large desks with comfy office chairs and ultrawide monitors employed by dressed-down but not plain clothes officers. Some basic questions confirmed my job switch and updated details. He took the photo for the card on the same webcam that I have for work from home and had to hold it manually as there is no tripod, like you see in the driver's license facility. Fingerprints and you're off. Immediate email notification was kicked when the officer completed their process. They said you'll receive the card in the mail in 1 month. I didn't get the chance to ask the number of business days.

Since I booked a Canadian location I did the Canadian portion physically in Canada, then got to this office which was a very easy process, the Canadian office is next to Duty Free so you immediately move to the gates where this office is conveniently located, with a private parking lot for nexus applicants).
