<p>If you want to get into banking you’re off to a good start with your admission to CM. The next steps are to get excellent grades (ideally 3.7+), high GMATs (700+) and great work experience. Leadership in ECs can be helpful but I think you overestimate their importance.</p>
<p>You seem to think you know a lot about the investment banking world. As a high school senior you would benefit from staying more open minded and trying to learn from people with more experience (i.e. bomerr as clearly demonstrated from his posts).</p>
<p>Some of your assertions are flat out wrong - “As I’m sure many of you already know, moving up the IB hierarchy for any serious employer is going to require an MBA from a prestigious institution.” Promotions in I banks do not require MBAs. They can be helpful, more so in some situations than others, but there are many very successful bankers who don’t have MBAs. </p>
<p>I suggest you work hard, be a little more humble and utilize available resources, especially people with experience who are willing to provide guidance.</p>
<p>Good luck.</p>
