i would say, for whomever is interested, a couple days before the interview in Frankfurt, that we should make some kind of pre-contact. One thing that i have proven to be very useful is to know someone to talk to during the waiting minutes in the lobby. Maybe go for a coffee before the interview, and for a beer once it's over. I dont know, it helps overcome the nerves.
On the other side, i wouldn't reveal any real names here, or emails. So we have to find a way to add each other to face book or msn without revealing any personal info on the open forum. Maybe private messages? Feel free to PM me and ill add you to my facebook. Note that im invited to the Frankfurt intervew.
