Here I am giving you some ways to become an Investment Banker

Make sure you are creating presentations with spreadsheets attached.
Microsoft Excel and Powerpoint are mainstream. Don't spend as much time with alternate programs.
Try for the big investment banking firms such as well known firms in New York or London. Getting an internship at a smaller investment bank is really just about as good. These firms are called “Boutique Investment Banks” and exist in many cities.
There are many reasons why a smaller bank may be easier to get an internship at. It may be in your town. There may also be a firm that is more specialized to what you have done. (For example, say you have interned at an airline.
There are a couple boutique firms that pretty exclusively lease aircraft.) There may also be less competition. Lots of students haven't heard of the boutique firms.
You can also get a summer internship at a regular bank (not an investment bank). That is not quite as good, but would still give you a huge leg up.
Join the investment banking club at your school, if there is one. That is a great way to network with potential employers.
Join Linkedin groups for investment banking.
Talk to alumni from your school that have recently joined investment banks. You can contact them via Linkedin or Readyforce or even Facebook.
Ask them to lunch (if you are local) or a phone call if you are remote.
Don’t be afraid to travel to another city to meet people, if it will help you find better leads.
Several popular websites and blogs cater to investment bankers.
The language used is specifically aimed at finance professionals and reading gives you a better idea of the banker mindset.
