Questionnaire that is done by two people, and compares answers at the end

I am looking for a questionnaire that allows two individuals two do the questionnaire. At the start, the first person fills it in and eventually the second person. At the end of the questionnaire, the results are compared to see where they interlink/agree with each other.

Preferably a WP plugin. Any ideas where I can find this, or any developer that can build this?
