Cultural Tip
The construction « X, il/elle fait quoi ? » is a hallmark of informal French, especially among younger speakers. It adds a slight emphasis on the subject and often conveys a tone of curiosity or mild surprise. In formal contexts you would replace it with « Que fait X ? » or « Quel est le rôle de X ? ». Also, note that “prof” is widely understood but still slang; in a formal email you’d write “professeur”.
