I put my Google Voice on my resume (and other places like my .sig) and I generally just forward all GV calls to VM.
If they care to leave a message or send a text, I may read it. If they don't then I ignore (unless I'm expecting a call from that number in which case I'll call back in a day or two).
Sometimes (like when we were looking for a nanny a few years ago) I may let GV actually ring on my main line.
