Interview questions for culture fit?

I'm working on a website that can be best described as "OkCupid crossed with LinkedIn". It aims to help employers and potential employees to figure out if there is a good fit between professionals (whether they are looking for a job or not) and their positions within the team.

Like OkCupid, the idea is to have a catalog of questions in different topics, and everyone can say what they would like to "hear" from a good match. Questions range from interest in company practices (remote vs office-based? what do you think of pair programming?) to preferred management approaches (Do you like to work within a Scrum setting? What is your approach for Buy vs build? ) to opinions about technology stacks and even general cultural values (Do you contribute to open source? Do you think it's important to have side-projects?). As more people answer more questions, it will be able to have a "affinity score" between people and if nothing else it could work as an ice-breaker during an actual interview with a candidate.

If anyone here would like to take go through the questions and help me come up with more ideas.
