Make a Real Contribution
MSI interns make substantial contributions to the projects and teams they work on. Hear from some of our intern supervisors about the impact current and past interns have had.
The Financial Management Team intern [supports] us with simple to moderate budget tracker fixes... elaborating on training draft documents for project management teams, and other tasks as they come up. This frees up time for the rest of the team to work on more complex tasks.

Director, Project Financial Management
Our interns serve as reverse mentors for me and MSI. They bring a fresh perspective, ask questions that we sometimes take for granted, and are an energetic set of hands. Our interns have... helped us see our important global work with a new set of eyes and ears.
