Investment Banking

The starting salary of a Bank PO is somewhere between 30-35k and various other benefits depending upon the bank. The total package goes around Rs. 4-6 lakhs per annum depending upon HRA (House Rent Allowance) for a particular city.
Now, after the seventh pay commission is applied (would be done in coming few years) the salaries are sure to rise somewhere between 30-70%. Also, we can expect an annual increment in salary based on increasing DA (dearness allowance) every year.
Add to it a promotion every 4 years (on an average) and a corresponding increase in your salary and benefits, I would say that any Bank PO employee is "settled".
Though it is a far fetched guess, in 10 year time you can expect a salary of 70-100k per month in hand, with many other benefits.
Please understand that in any job (government or private), it takes around 10 years for you to achieve a level that commands good salary, respect and host of benefits. So if you are preparing for an MBA, only look for colleges that can give you an opportunity to get at least a package of Rs. 12-15 lakhs per annum today. My suggestion would be to choose only from top 15-20 B-Schools.

Join an Investment Bank as an Investment Banker. You may need to gain expertise in assessing financial risks and project viabilities to get the recruitment easier. Additional knowledge about the Banks activities in the area will be useful too.
An investment banker is an individual who works in a financial institution that is in the business primarily of raising capital for companies, governments and other entities, or who works in a large bank's division that is involved with these activities, often called an investment bank.
Investment bankers often work at investment banks, the largest of which are Goldman Sachs (GS), Morgan Stanley (MS), JPMorgan Chase (JPM), Bank of America Merrill Lynch (BAC) and Deutsche Bank (DB). Whether or not they work for a true investment bank, investment bankers assist in large, complicated financial transactions. This may include advice as to how much a company is worth and how best to structure a deal if the investment bankers client is considering an acquisition, merger or sale. It may also include the issuing of securities as a means of raising money for the client groups, and creating the documentation for the Securities and Exchange Commission necessary for a company to go public.
Generally speaking, the investment banker will save the company in question time and money by identifying risks associated with a project before the company moves forward. In theory, the investment banker is an expert in his or her field who has a finger on the pulse of the current investing climate, so businesses and institutions turn to investment bankers for advice on how best to plan their development, as investment bankers can tailor their recommends to the present state of economic conditions.
An investment banker serves as a facilitator between a company and investors when the company wants to issue stock or bonds. The investment banker assists with pricing financial instruments so as to maximize revenue and with navigating regulatory requirements. Often, when a company holds its initial public offering (IPO), an investment bank will buy all or much of that companys shares directly from the company. Subsequently, as proxy for the company holding the IPO, the investment bank will sell the shares on the market. This makes things much easier for the company itself, as they effectively contract out the IPO to the investment bank. Moreover, the investment bank stands to make a profit.
