Final Interview to 'Happy e-mail': They tell you to wait for two or three weeks, we got our answer in 9 days! there's groups that took more and some that took less.
KSIMS83: send me a PM and I'll get back to you.
Don't need an invitation for the OD...just show up there tidy and smiling and that's it!
If you applied online for an OD, they will shortlist you in about 7 or 5 days prior to the event, so be patient.
For all those who supported me...THANKS!

Good luck!
