This Internship Report is a final requirement for the M.B.A. program. As a part of the internship program, I was placed in “HSBC Bangladesh”. The topic of my study is “Assessment of Customer Satisfaction on Bank Services: A Study of HSBC Bangladesh”. The objective of the report is to maintain a balance and forecast on the Customer who are the more crucial party of all banking facilities. The bank cannot be run in a over fledged way if the customer base is too weak. To retain the existing customer and to create a policy to cast new customer in a bank, a bank is always busy and concentrated. HSBC is not the exceptional. As of December 2011 HSBC has already more than 1,62,000 customers where 1,39,000 customers are always active and almost 27,000 customers are enjoying the banking business being a small active through Unclaimed and Dormant Account maintenance.
