“An internship is essentially a three-month interview”, says Stephen M. Rakas, executive director of the Career Opportunities Center at Carnegie Mellon’s Tepper School of Business. A half hour interview can be a minefield, so you can well imagine the potential for slip ups over three months – though, of course, one can offset this with the greater potential to show of what you are capable. In this article, career services directors from three top business schools share examples of MBA internship mistakes…and how to avoid them.
Mistake 1: Not knowing the company culture
Failing to understand company culture can cost you the internship, as well as a full-time job offer. Rakas says that it’s “critically important” to understand company culture from the beginning, since, “It’s very likely that people who work closely with you, as well as others who barely know you, will have a say in whether or not you receive a return offer.” If you do your research ahead of time, you will be better equipped to demonstrate that you are a fit.
How can you learn about company culture? You can start by networking. Rakas states that MBA students should network with alumni, as well as people in their extended network who are currently working at the companies they are interested in. “The more people with whom you develop a positive rapport and who can speak positively of you and your contributions, the better.” You should also do your own research and pay attention to details such as how communication is handled.

Mistake 2: Not having a pre-onboarding meeting before the start of the internship
According to Kristy Posocco, deputy director of the Career Development Office at the Yale School of Management, one common mistake made by MBA interns is not contacting their supervisor in the weeks leading up to their MBA internship. Posocco advises that MBA interns have a pre-onboardingmeeting with their supervisor in order to “ask questions that will expedite their on-boarding and equip them with the knowledge and insight to begin immediately adding value when they hit the ground”. Questions you should ask include:
- Have business needs shifted since you spoke during the interview process?
- What does a successful end-of-summer deliverable look like?
- What do key milestones look like?
- What has characterized the most-effective interns in the past?
