Pros
PC Connection provides a lot of product training and access to tons of information for its inside sales reps. If you are outgoing, you might enjoy working there. They have a good benefits package and often provide free food. It's basically a commodity sell, so you need to build relationships with buyers who value your responsiveness. You need to put a lot of hours into the job during your first year, to research your leads before you call them. Once you build your "book of business," you can do a lot of repeat selling and make good money.
Kontras
The sales force is housed in a very large room subdivided by cubicles. For me, it was too noisy. My sales manager (who is still there) forced me to relinquish my first steady buyer, even though I'd earned the account and followed all the rules, just to satisfy some political deal with another sales manager. I was given another account that didn't plan to buy anything. After that, I totally lost my motivation.
