I would agree. Though C is far from useless, it really isn't used here at the Creek. Which was a double bonus for me, since after 6 years immersed in C and C++ I could find a job that let me do something new but that I felt very comfortable interviewing for. That said, I really don't believe you need lots of C experience to do well in our interviews.
