How would you react in an interview in which the interviewer is just trying to get free advice?

Howdy,

I use a lot of innovative tools and techniques. I use a power-dialer that makes 5 parallel dials at the same time; I have a virtual extended team that's able to do menial work, such as data entry, web searches, and photo-shopping; and I also use web-scraping to develop lists. I've a lot of successes using my methods, techniques, and ability to problem-solve.

Anyways, I'm worried about future job interviewers who are only interested to know my methods, since none of them are doing these tactics. I'm worried about an interviewer not interested in my candidacy as a salesperson, but instead, my methods. I quickly get paranoid about this when an interviewer asks me about "which criterias do you use to determine the optimal conferences to attend?" (not at al my domain - this is marketing's concern); "how does that power-dialer work? How many dials are you able to do? How many connections do you get?"

I know that I'm being exploited when I'm being asked a follow-up question to a question that I haven't even finished answering, and both questions aren't even related to the job that I'm interviewing for.

Finally, I was played before quite a bit by hiring managers. Last year, one lady "interviewed" me for pointers. However, I noticed that the company never hired anyone to fulfill this job requisition.

How do you deal with this?
