Wow.

As a fellow sophomore, you need to realize that nobody will do the work for you in this industry. Networking, researching, and pulling all nighters is the name of the game if you want to make it.

internships.com

never anything great on there but if you are a sophomore you might find something decent. Also, if you set the email alerts for a key word like "finance" you well get notified once a week for new ones that came up.

linked in and indeed is pretty good. Also, cold calling wouldn't hurt.

Although others here were pretty harsh about it, it's true that you need to look for opportunities yourself. There's a very small chance any "central sites" you might find will be of any use, mainly because companies receive huge influxes of resumes online every day and have no reason to spend any more time on yours than all the others. The key is to differentiate yourself by networking, and hopefully getting someone to recommend you for an internship. If you haven't already, you can start by attending events sponsored by the career services department of your school. You will find potential connections there as well. Your school should also have a job site with listings from companies looking to recruit there. Good luck.
