During your interview, request the officer for oath after November. It may or may not work. If someone can check your mail while you are out of the country during the 2 weeks in November and if there is a letter from USCIS, open and read it and save it for you. If the oath falls during your trip, then send a letter to USCIS by certified mail to reschedule the oath date. This will add unspecified delay in your case. Make sure to NOT let the oath letter go unanswered, otherwise USCIS can consider the application abandoned. Remember, you are not a citizen until you take the oath.
