I have used these with advanced students. They are great and the full range can be found HERE. This blog post I made, has further resources and ideas for using the Proust Questionnaire.
Each have basically the same questions. So once the students know the questions, you can use multiple times. Further, I usually would photocopy two copies. On one (A) - erase out the answers.
On the other (B) erase out the Questions. So when A-B do the interview, they have to listen carefully to each other and/or write the corresponding information.

Also visit Proust.com for a nice alternative way to use these questions. Students invite members and write answers to the questions.
Here is a video version of typical Proust questions. Might be useful for doing a listening activity. Pause and get students to answer his questions then listen to the video answers.
