Is this hire critical in terms of timing? If yes, then I would go with the other's suggestions of doing a trial period. Provide feedback and positive reinforcement.

If no, then I would absolutely hit the pool again and find someone who's both a technical and culture fit. This post might be helpful for you: http://actionablebooks.com/culture-fit-whatever-that-means/

Also, how big is your team? If it's small enough that this person would throw off the flow and stick out like a sore thumb, then I would say no again.

Good luck!
