If you ask someone to bring their own code, you are assuming they have some code to share that they are also confident enough in to bring. I can see lots of people agonizing over this. Even if you've got a relatively broad base of shareable code you've written, what's right for the context of the interview? It would be stressful for a lot of people, probably more than just doing a coding exercise.

I'd suggest giving people another option as well.

I thought about this and we have a backup problems in place if they don't feel comfortable sharing. The context will be the same, both the candidate and the team member will be working as equals to address the problem. Although, in this case, the team member is already familiar with the problem.
