That’s great news that you are in consideration at this final round! Since you are interested in working in either function, I would recommend you continue to express your interest to all parties involved so that they are aware that you would take either position. You could share this with them in your thank you note post interview or when you talk to the recruiter or hiring manager next. Best of luck!
