My employer is gigantic and well-known and this still happens. I refrain from looking at a resume before an interview, the recruiter just tells me what to interview for (front end developer). I start basic, like "Write a 1-5 star rating widget in HTML", I even show them a picture of what it should look like, only to be met with hmm and uhhs, some broken, invalid HTML, and not a single line of working code written. In one instance, the candidate attempted to surreptitiously call their friend for help (it's very obvious because I heard the ringing tone). Later, when I actually look at their resume, I find the expected flowering claims of 10+ years experience in front-end and whatnot listed on their resume. What a waste of time
