Sometimes if the bank that she is willing to work in got a central head somewhere else in a different country then it might take that much of time. What I meant that sometimes the HR or Recruitment department would be in a different country. Not sure if that is the case with this bank.

Cheers buddy, everything would be fine ... If they got some issues then they will tell her that we will call you within a week or call you later [goes for most of the companies here if they are not willing to really hire you] 

Best Regards
