Goal of the Interview

The interview is designed to assess your academic potential and your ability to learn, think independently, adapt and engage with new ideas.

You might be asked about a mathematics problem, be invited to discuss the different aspects of a physics exercise or have a conversation on a scientific publication.

Whatever form the interview takes, we are looking for qualities such as perseverance, enthusiasm and creativity. Keep in mind that many questions are designed to test your ability to apply logic and reason to an idea you may never have encountered before, so don't worry if the interview is about a topic that you haven't covered yet.

Watch our MOOC to best prepare for Higher Education

Ecole Polytechnique created a MOOC called "Mathématiques : préparation à l'entrée dans l'enseignement supérieur" (Mathematics: how to best prepare for Higher Education). This MOOC is only available in French. They are a great opportunity for French-speaking candidates to prepare for the oral exam for the Bachelor Program.

French to English vocabulary glossaries for the oral interview

Two students of Ecole Polytechnique's Ingénieur Polytechnicien Program have created two French-English glossaries to help Bachelor Program applicants prepare for their oral interview: one in mathematics and one in physics. Thanks to Anthony Guillen (X2016) and Ayman Idrissi-Kaitouni (X2016) for their great work!
