I applied on the 3rd and am still awaiting selection. I would imagine that 2-3 weeks would be a reasonable wait limit. Having to narrow down circa 10k applicants isn't easy in the short space they have. Don't envy them at all. On the plus side, if you've got to this date, your application has passed initial screening and is awaiting a human to read the essay questions.
Good luck, fingers crossed for us both eh!
