I received it October 8th (they give you 5 days to complete it or you're out, sort of like what the CRS email had also said)
Think it took maybe 15 minutes max? Believe they say it takes 5 but I was reading each option carefully and ticking my boxes of traits each question (which I'd written down rather than having as a spreadsheet in another tab because they track your mouse movements). It definitely felt short since I ended it feeling like I'd been able to focus as much on the last question as I could on the first.
Hope that's useful!
