Just came back from the test/interview. Test was a little harder than I expected. Same questions you can find on Citizenshipcounts and Yourlibrary but asked in a bit different way. If you can do those tests, means you will be good with the real test too. Took couple minutes to respond to questions. Got 19/20, not sure where I made a mistake as I was sure I was right on all of them. This does not really matter as long as I passed 15. I first responded to all those I know, marked those I had a little doubt with. Was planning to go back to them when done. When done, did not go back to those I had doubt with because even if they were wrong, I would still pass. I wanted out asap.
Interview was not an interview, she quickly checked my docs in less than a minute, asked to sign a document that says that all info provided until today is correct. She asked whether I intend to live in Canada if granted citizenship, I said yes, they marked something. She spent 3-4 minutes checking my 20-25 stamps. 3-4 were missing, she did not care. I did not translate non-English stamps even though it was requested on the invitation, she did not seem to care either. And then, standard "you will receive invitation to oath in 1-3 months."
Total time spent was 50 minutes. Hope this helps. As you understand, I cannot share the questions I had at the exam.
