In addition to the resources available at the CMC (JTS, emails), here are a few useful resources that would help you in your hunt for internship/full time jobs.
1. Internal Google Worksheet
Internship Job listings from last year (2011-12), compiled by Jenny Delaney for the class of 2013. These jobs may no longer be available, but it's a good starting point to start looking for similar postings. The class of 2014 should go ahead and modify this spreadsheet with another tab for 2014.
2. Ventureloop
For the folks interested in working at venture backed startups, this is a good place to start.

3. Internsmatch
Another useful resource for internships. Caution that this does not only focus on MBA's
Stay tuned to this post for more updates and resources.
Good luck!
