Yeah this comment thread is certainly enlightening in that regard. Maybe I should rethink my strategy! May I ask what you market yourself now?
Meaning: It's imperative you explain there is a focus on what you're specialized/interested in. And if they're still interested there is a lot of extra goodies you know as well. But only as long as it's part of the assignment/position you're interviewing for.
I know this answer is a bit vague, but I hope it was still to some good use for you.
