Svantaggi
Don't get too excited about the higher pay comparing to local banks. They may pay you like 1.5 person, but they will make you work as more like 2 or 3 people. You will constantly wear several hats. Currently under the tight budget control, overtime is almost not allowed. You will probably end up with losing personal life and not getting paid for overtime. When you decide to leave, you are over qualified for the same role in other banks and no one will pay you the same, you are doomed.
