Pros
If you aspire to be a sales person, I think they teach good discipline about smiling & dialing and honestly qualifying a sales opportunity.
Cons
No respect for marketing as a contributor to business success. High churn overall and especially a revolving door in the marketing department. Company is 100% sales focused. I joined the company because I had a great set of interviews with the Marketing Director. 2 days after I joined, the small marketing department went out for drinks to celebrate the fact that we had completed our annual metrics a full quarter early. The next day the Marketing Director was fired, presumably because she asked for a promotion or a raise or something, which, evidently, she deserved. That kicked off a year of hell where I worked my butt off and then I was unceremoniously fired by the Marketing Director's incompetent replacement. That replacement Marketing Director lasted another month before he was fired. Wow! Shameful!
