You can begin by asking how they ensure quality on their projects. They will hopefully give you an answer that shows they really believe in standards. For instance, your candidate might tell you that quality is not only satisfying user requirements but also delivering a solution that is truly maintainable in the long term. And keep in mind the difference between quality and elegance. The most elegant solution isn't always the one of the highest quality.
Elegance can fluctuate depending upon budget and time constraints.
Never compromise quality. Some might say there's little difference between an architect and a project manager. I say there's a lot. Project managers are responsible for budgets, timelines, people issues, business knowledge, and owning the client relationship. That client could be someone paying your company for services or it could be the internal marketing department.
