The admission interview of Ecole de Conde aims at verifying that your personal project matches the curricula offered by our schools. There is no need to prepare itself in a specific way.
However, it is helpfull to ask yourself a few questions such as : Why this curricula in particular ? Why Ecole de Conde ? What is my professional project ? What critical eye can I have on my educational pathway ? etc. Knowledge of cultural references in relation with the envisaged training program is also a valuable asset.
Even if an artistic portfolio is a valuable asset during your interview, it is not mandatory. Many students integrate Ecole de Conde without any prior artistic practice and improve rapidly to a satisfactory level at the end of first year.
