Pros
You get to come in with little to no experience and learn all about sales. The product basically sells itself and you have very few objection to overcome. You'll get TONS of training and are able to network with partners to grow your book of business.
Cons
Management has been hired from outside of the company and come in knowing nothing of the software and cannot answer even the basic questions. Very clickish, if you aren't cool with management it's hard to move up even if you have the experience and are well qualified. Typically they hire their friends within the company or whoever sucks up to them the best, which is typically the people that are the least qualified. They hold meetings at THE WORST time and are typically talking about things you already know, but remember, management is hired from outside of the company, and they are trained by the most tenor people on their team. Also they don't pay industry standards and expect to maintain people after NOT giving a descent raise.
