I don't know if I should consider my interview a success, probably not. I didn't have my passport with me (long story) and the agent told me she would absolutely need the copies, which I sent a week later.
So it's been around 50 days, or less if you count business days only.
My wife's process took 11 months (around 10 to decision made), so I am not particularly bothered by the delay. What really annoys me is that I am always checking ECAS, but that's a bad obsession habit, not CIC's fault for sure. At this point, not feeling like I need to check ECAS is my main reason to get this done.
