Pros
WebMD Health is a name that is recognized by many people in the general public, which is unusual for a company that is involved in healthcare education and communications. This is largely due to the widespread advertising campaign used to drive traffic to its family of websites, which are targeted to consumers (webmd.com) and to healthcare professionals (medscape.com; theheart.org, emedicine.com, etc). The opportunity to work in a company whose mission is to deliver high-quality healthcare information to patients as well as healthcare professionals is a rewarding one for those with strong interests in medicine, science, and/or public health.
Cons
Unfortunately, the amazing potential of this company is limited by poor communications between management and employees (ironic since the company specialized in communications) and by poor management in general. The organiziation somehow manages to succeed despite the poor management -- likely because there are many talented individuals working there. To succeed and be happy working at WebMD, an employee must be self-motivated and be able to find satisfaction in his or her work without expecting to receive any sort of praise from their managers (there are a few exceptions to this, of course). Often, the only type of feedback received is negative in nature.
