Quick background: I'm a solo founder for a company which has gotten an initial round of funding from a VC firm

I built the app from scratch (tech background) and am learning the business side of things along the way to another round of funding

I'm in the Midwest where there is a tangible startup scene, although my network is limited right now -- I'm seeking advice on ways to approach vetting candidates as I find them.

For a more "tech-y" person, baseline questions about development experience and knowledge seem appropriate. However, the person really just needs some programming chops in my mind, and not a rigorous understanding of CS theory. What are some ways to gauge the more intangible qualities of consistency, motivation and/or diligence for dev?

For a more business / marketing person, what besides the candidate's experience (and my own "read" of the person) are telling traits for a potential fit?

I'm of the mind that this process will take time and needs to be done carefully. HN's collective experience seems like a great place to glean advice from, thank you all for the thoughts that you share.
