Vantaggi
New management is engaged, opening lines of communication and growing the branch -- budget, headcount, resources, etc. There is a feeling of positive change and motivation that was lacking under prior leadership. The momentum is exciting.
Svantaggi
Here you must roll up your sleeves, but you also get to see and impact everything. Some people find this invigorating and empowering. Others find it frustrating as they want to focus on their narrower roles. If you prefer the latter, a smaller foreign branch (NBK or elsewhere) is not for you!
