Pros
Great training. I had formal training when I started, got to shadow reps in the field, and my manager went with me on lots of calls. They fly all "Executive Reps" to Dallas for training 4 times per year. A former regional manager and the VP of Sales run the trainigs and they are very interactive and high energy. Comp plan is really awesome. My base went up $20k after I'd been there around 2 years and sold a certain amount. Several of the people I worked with earned over $100k in their 2nd year out of college, and a couple earned over $200k! Great people. Managers and co-workers are very passionate about their jobs. When you sell a big deal, all of your team-mates will send congrats emails and make you feel great about your accomplishment.
Cons
The sales-rep job is only for people who are career oriented and want to compete and grow. If you're just looking for a job, and want to put in your "40 hours per week", this isn't the position for you.
