I had my stage 3 on Thursday and am dying to find out, how long before they got back to you??
As per the posts above, the standard seems to be 2 days, certainly was for me. Bear in mind that, at least when I did mine in the summer, the ATCO and HR from the interview post (or perhaps courier?) the paperwork back to Fareham after the interviews, so Fareham won't know until at least a day later...
