Without rating the interviewer's viewpoint about big risk in this regard, I would suggest to learn about ASIC design. So you are able to answer related questions, show that you are aware of difference's in design methodology and give the impression that you're able to cope with new challenges.
This won't help if the interviewer is primarly looking for "intelligent apes" who are used to operate a specific ASIC design tool, but surely if he's assessing problem solving capability.
