Hey guys.
Got the invitation too, NTR. I've just accepted the latest slot available (11th Apil) as I had no time to check my own calendar...
I'm not sure if I'll be able to attend, does anyone knows if it actually affects your application cancelling? (the PDF says they will reconsider you three times) There is no further slots available at this moment apparently as I only have the option to 'Cancel Interview'. My idea is to re-schedule for May.
