It depends on the project, and I know some interviews are tough, but you could talk about other interesting that could complementary with your DP work.
The other day, someone talk to me about working as DP in a 48 hours project, in which you have to write, film and post produce a short film in a weekend.
Well, I am sound engineer, and even if I don't be checking or working in the sound department, the director saw that as an asset because I could help in post production. Same thing if you are good with editing (but maybe in a feature, is not the best option because as DP you are too close to the footage). Also, if you are good writing scripts, you could help in the pre production.
The other day I was watching an interview with Geoff Boyle, and he says that every DP now has to know a little about post production, color grading, CGI, etc., because if you know that, you can save time when shooting (not to fix things in post, but to save work to later in post, not the same thing) and if you save time, you save money, and increase the chance that people call you again.
Just my thoughts on the matter.
