Only thing I can confirm is the title, as I seen it on my friend's business card.
But Citibank working culture is well known for being very competitive and demanding.

Not to sure how it works for Citibank, but in most cases programme like these don't give you the option to change. Unless you're really outstanding or you can justify your reason. A simple "I prefer that" doesn't work any more these days.

Not really. These banks accept a variety of degree holder into their bank. Basically they look for people who fit their profile. However unless you're dealing with very specific jobs in the bank, then yes you may require or they would prefer people with finance back ground.

Hm... the one on their website says otherwise(that look pretty promising). Anyway if you're looking for a good starting platform with a bank. Citibank pretty good on top of that the GE programme don't just hire any tom d*** and harry.
