This coincides with the rise of the power of HR departments. An HR person can't POSSIBLY correctly evaluate a candidate for a technical position. All they can do it pick the best sounding resumes. That lets in many charlatans, and rejects many competent candidates. Even if the process does involve a later technical interview with the department needing the new hire.
Nothing new though - I've seen plenty over the past 28+ years since graduating. One involves a job where I was placed by a placement company and then when the 6 month contract was up, I was hired. Since they did so well with me, they went back to the same source for a second hire - the thing is, the placement company wasn't really equipped to vet candidates based on technical skills, so they sent over this guy who claimed the same development experience as I had, give or take, using the same products. Well, it only took a few weeks before the rest of us figured out this guy didn't have the slightest clue, and soon we were back to a 3 man team. Another incident occurred at my next job. We were a small company, so the interview process basically was the prospective employee talking to a bunch of us and we would ask technical questions based on the indicated experience level of the candidate. We rejected a lot of people before our boss (the owner) even talked to them. Somewhere along the way he got the idea we were just being too closed as a team and didn't want anyone else in, so he himself interviews this guy and hires him. Supposedly an expert at using web services on Microsoft servers. When he had to enlist help to get IIS installed on an otherwise new, blank server he was give to use, the truth was evident.
But in today's HR driven company, if my coworker and I both applied for a job at one of those places, odds are my resume would be immediately tossed, as my coworker has Microsoft certifications that I don't. However, if you look at the level of projects I complete vs what sorts of things he works on, it's readily apparent which of us knows this stuff...
