Under NDA, so can't reveal much.
Do you need help with something?
Here's a start: never negotiate with the HR or IT depts.
Always attempt to negotiate with someone who would promote your inquiry to the board of directors. VP of operations, VP of business development, etc. Keep in mind that for large banks this isn't a game they would be interested in, if it's an EMD then a smaller bank would give you a response provided you play your asking numbers wisely. E.g. expect to hear back anything from $xxx to $xx,xxx.
