Yeah I know that feeling, but I believe it’s nothing to worry about, rest assured. When I was a student I had applied for a work permit too and they called the employer who had given me an offer and asked all sorts of weird question. At the end it was approved so all went well. If you’re curious about the insights of your application, request for GCMS notes through the official government website. It’s only 5$ and you’re eligible to apply for it yourself since you’re also here in Canada physically. Cheers and rest assured, all should go well.
