Been there, did that.
Some insurance companies will recruit marketeers/salesmen by inviting any and all job seekers they can find, regardless of the career field, experience, or preferred market of the job-seeker. Think of it as casting a wide net and see what fish takes the bait (to use a poorly mixed metaphor.) They may send out 1,000 invitations and get 20 replies. Of that twenty, perhaps 5 will come to the next job seminar and perhaps 1 will go so far as to become an independent contractor/salesman for the insurance company. Some can make a successful living at it, others cannot.
If they become salesmen for the company, they'll be provided with leads, hundreds if not thousands. Of those thousands, maybe 20 will respond when called to set up a meeting to review their insurance needs/sell insurance. Of that twenty, perhaps 5 will sign the contract and the salesman will get a percentage of the proceeds from the sale for as long as the insured keeps renewing the contract.
No experience is required by potential salesmen because many companies pay purely by commission. If you don't sell the provided product, the company doesn't suffer any loss. On the other hand, it's hard to sell someone something they didn't need last month, last week or yesterday, and with any hope they won't need tomorrow, next week, or next year.
