hi doc carl. usually interviews are for clarificatory purposes. karamihan ng mga interviews revolve around CLP which is not your case. so most likely it will be on your work experience. you are lucky for the vo to have granted you an interview. i remember dati sa isang post na may isang questionable entry sa work experience and pinapadala lang sa kanya ang explanation by mail (kasi may mga discrepancies). After that, its unfortunate na na-deny ang application. for your case, just present the necessary documents to justify yung mga affiliations mo. that will seal it and most likely issue na agad sa iyo yung MR. Good Luck!
