Pluspunten
MasterCard was a great place to intern. We had a small intern group spread across many different areas of the company, but our departments and HR made sure we felt welcome and integrated into the organization. They have really thought through their internship program and had weekly educational sessions focusing on resume writing, knowledge about the bank, personal strengths, etc. We even visited the floor of the NYSE! The hours were great, the work was not overwhelming and was appropriate for my level of work experience at the time, and my coworkers were infinately helpful. Overall, the atmosphere and people were just perfect for me.
Minpunten
It was a sophmore internship, so it is not like other financial internships where you can expect a fulltime offer after the internship. Really, other than that, I can't think of one negative thing.
