In your last job as an account manager, what did you sell?

"In my last account manager position, I sold an investment research SaaS product to institutional investors. While this wasn't advertising-related, it taught me how to help clients use an online service. I'm very accustomed to walking clients through logging into websites and using them, which I think will be similar to helping clients use Facebook's advertising apps. I feel wholly confident that all of the skills I honed in my last job will transfer and allow me to be successful at Facebook."
