Once again, let me remind you I'm still in the business, and I can tell you it's not as dead as you think. It's difficult for a reason. Back in the 80s, there was a huge expansion in radio. Docket 80-90 added hundreds of new stations to the dial. Radio stations needed to staff them, so they were hiring like crazy. In my view, the talent level for some of those new hires wasn't all that great. The standards dropped from when radio was primarily an AM medium to when it expanded to FM. People didn't need the great voice to get hired.
So maybe it's good that radio is being more selective in the people they hire now. As I've said, the resumes I see are incredible. And you're right, a good aircheck is only a small portion of what they need. They will need social media skills, digital audio editing skills, and even video editing skills. If they want to be a PD they need to know all of the digital music scheduling software systems. Yes, it takes a lot more to get hired. But most of the good schools are teaching all of this.
