I hate to be a downer, but yes, your age probably precludes you from getting an entry-level job in investment banking.
Quite simply, IB is a conservative industry that rarely ventures outside of it’s typical mold in the recruiting process. There are a couple of reasons for this. For one, IB is extremely hierarchical and people will be very skeptical of hiring a junior that is several years older than the rest of the junior/mid-level managers. Second, IB analysts are expected to essentially give up their lives (80+ hours a week) for a couple of years in exchange for compensation and advancement opportunities. You’ll have a hard time convincing them that you’re truly willing to do this at 30 years old.
Also, not sure what school you’re attending, but most banks are pretty particular about which schools they recruit from (continuing the theme of conservatism). If you don’t go to one of the “right” schools, you’ll have a hard time getting an interview, let alone a job.
If you’re really set on getting a job in IB, I would focus on your efforts on networking with boutique firms in non-finance center cities (basically everywhere except NY and SF). These firms will be less attached to the “traditional” path, but it will likely still be an uphill battle.
Traditionally, internships are given to rising seniors (to convert them to full time post graduation), but smaller firms like the ones I mentioned above will also hire sophomores occasionally. I would focus your efforts on getting your hands on any kind of relevant experience you can find. If you’re looking for a place to start, I’d suggest Private Wealth Management offices – they’re everywhere and you can learn the basics of finance in a practical setting.
As a backup, I would suggest considering paths in wealth management (as I mentioned above) or in more traditional corporate finance roles (entry-level positions are commonly called financial leadership development programs).
Good luck!

P.S. Check out Wall Street Oasis (google it) – it’s a forum like this, but it’s focused on finance careers, so it has a lot more useful information for this topic than CC.
