Good old recruiters
I had a recruiter encourage me to overstate my experience with Cisco switching / routing gear, when really at that stage in my career I hadn't done much more than check if a port was showing as up or not.
I didn't want to put myself in a position where they test me on that subject and I flail, so I suggested we left it as is - the job was a junior role anyways.
Fast forward to the interview, they say almost immediately "We saw you're a Cisco EXPERT on your C.V, can you talk us through some networks / projects you did?"
