DevOps is a culture not a job.

Most good candidates know this, and will actively avoid "DevOps" roles.

Now someone claiming 10 - 16 years experience as a DevOp, is : A: Lying. The term is 6-7 years old B: If they have even been using / administering computers for that long should know what a default route is.

Could they have misinterpreted the question? I know the even at a senior level, interviewees can get flustered and confuse themselves.
