I've heard that from someone else and I almost can't believe it. My non-coding friends could write the pseudo-code for that, which is a pass in my interview loop. It's a trivial exercise in a 100-level coding course.
Part of the reason for this is online job postings.
The good candidates apply to some jobs, get hired, and stop applying. Some terrible candidates will apply to hundreds of jobs, never get hired for long, and just keep applying on every job posting. So a small minority of terrible coders end up being a disproportionately large fraction of interviewees.
