Sadly true. In my last set of interviews for a web developer position at Google, I aced the questions from fellow web developers, questions relevant to my experience and to web development. Then they sent in a "software engineer" (who probably couldn't code a rich web app to save his life) who asked a disjoint set theory merging question that I struggled with. He grimaced at my "incompetence" and at that moment I hated backend engineers and their superiority complex. Naturally I didn't get the job, but they had the nerve to tell me they gave it to a "stronger" candidate.
