I'm interested in the opportunity; however, I specialize in Y and Z. Would those skills transfer over well? / Are there openings in those areas?
A little grammar and spelling help
A potential employer is calling up regarding an opening in their company. In the middle of the telephone interview the interviewer asks, "Do you know how to write for X", and X is not your area of specialization. How would you express to the potential employer that you are interested in working for them but in other specialized areas.
