Hey caffy, I haven't given up with KA, but in my case it isn't appropriate to pin too much hope on getting past something that I clearly haven't done well in. I am now concentrating on getting into the "other airline across the road". Hope you get called up for an interview, that's where all the fun starts.
Everyone else, keep waiting and don't wet your pants just yet. I doubt they will keep their 3-4 week promise with everyone, so for the time being, no news is good news!
