It's central Europe, near to Switzerland, so, If you live in Australia as your profile says, then it will presumably take a little longer for the mail to arrive.
Hello to everyone in this thread,
I've also got admitted to RSC (Robotics, Systems and Contol) on Tuesday, March 1, and got the official letter 2 days later in the mail.
But no response regarding the ESOP yet, fingers crossed, and good luck to you all!
