Firms are involved in ENSAE's program in several ways :
- internships and projects, where students are trained to use the methods and models taught at ENSAE to solve real life problems. Students are strongly encouraged to carry out internships abroad (see the "internships" section to post internship offers)
- information on firms, careers and jobs, organized by the student association Forum ENSAE ; firms have an interest in making their name familiar to students who could be their future executives
- some firms organize specific training sessions, sometimes abroad, aiming to help students understand their industry and develop their abilities to be successful in their chosen careers ; such information can be passed on to the internship service or the Forum ENSAE
The alumni association (Anciens de l'ENSAE) plays a key role as a link between firms and students.
