I'd be working on Plan B...
Kouk,
First off, sorry for not getting hired by UPS. I was turned down in Sep of last year and know how bad that feels...
As for a second interview, I wouldn't count on it. I know several guys at UPS including one in Mgt and they have never heard of a guy in the last 2 years getting another interview. I think there are too many out there who haven't had their first shot yet to be looking at guys for their second chance. There are two guys on this forum--exp96 and HercAC--that were invited to the pysch test, but that's as far as they have gotten...
If you haven't been hired somewhere already, my advice would be to concentrate on your next "first" interview elsewhere...
All the best...
