I am looking for a few solid phone screen friendly questions with proven success to evaluate the technical competency of a candidate for a BA type position. I require this candidate, who will function between development team and business side/customer, to understand the technical side of things adequately to push back as appropriate on both business/client and technical/developer to achieve the right end goal for the customer.
I hesitate to use any truly developer-centric or code questions, since this person does not need to code (history of coding is not a bad thing), but they must understand technology and the technical challenges at an architectural level (in this case for a very large scale enterprise web application).
