MsRobyn is our current expert on radio, but I can share some experiences from my distant past.
The junior salesperson in any organization is always a butt-monkey. Every time the sales staff changes, the current staff picks over all the accounts and the new person gets the sucky leftovers.
Radio sales is pretty much just one step up from going door-to-door. Who are the current advertisers on the stations you listen to? Those are the kinds of places you’ll be going to, every day, in competition with every other radio station, television station, cable operator, newspaper and direct mail organization in town.
Your station has a “rate card” or price list with a bewildering variety of contract terms depending on length of commercials, dates, time of day and many other factors. Ignore them all, because almost every contract is individually negotiated. And in every negotiation your client will threaten to sign with all those other radio stations, newspapers, etc. unless you cut your price.
You’ll be working on commission. Not only that, but most companies have a quota. So if you don’t succeed you not only won’t get paid, but you won’t get paid and then get fired. That’s why radio stations are always advertising for new staff. There’s always the chance that someone new will do better than the people they already have.
As you’ve noticed, you won’t get a lot of support from the on-air staff. At best, you’re a necessary nuisance. And if you intercede for a client who wants something (tickets to a concert, meet a favorite air personality, whatever) you’re an annoying pest.
In other words, it’s a sales job, and not particularly better or worse than other sales jobs.
