If everyone one here had their say I'm sure they would all say ASA over PSA...hands down. But what it should boil down to is which regional do YOU think fits YOU. Are you really gonna let a bunch of guys you never met tell you where to work?? Do some research on the 2 companies and find out which one is right for you. And don't limit it to only those 2.....you have many other options, leave them all open for discussion.
P.S. what times did you apply with?
