Pros
Humana has a ton of training and resources available to learn the role and improve your skills. Training is divided between licensed and non-licensed agents so that everyone is training at their appropriate level. You get to meet a ton of people in your local community and provide value with the health plans. Once you get the ball rolling and take care of people, the referrals snowball allowing you to grow your clients.
Cons
Your experience will vary drastically based on management. You can either get no support or a ton. This can be difficult for someone new to health insurance, let alone Medicare, since it's highly regulated. If you lack the ability to engage with stakeholders (think doctors, non-profits, senior living communities, etc.) then meeting your sales goals would be very difficult. Wear and tear on car as you're driving all around.
