In Beijing, you don't have to be interviewed if you visa application go through CITIC. The Beijing embassy just needs you come over for fingerprint. I don't know the situation in guangzhou.
Go to visit the CITIC website and you may want to call them directly. I called their branch in Shanghai a fews ago. Suppose they could explain to you clearly.
