SAS Institute 2012 rank: 1 (2011 rank: 2)

Headquarters: Cary, N.C., USA

Software company SAS climbed to the top of the global list this year, edging up from the No. 2 spot it held last year. So what makes this company so great to work for? Well, for one thing, its leaders are certainly accessible. CEO Jim Goodnight hosts monthly “Conversations Over Coffee,” unscripted breakfast meetings that are open to all employees. These conversations are so popular that other division heads have begun to hold similar events for their employees.  

Google 2012 rank: 2 (2011 rank: 4)

Headquarters: Mountain View, Calif., USA

Google moved up by two spots in this year’s ranking of global workplaces. The highly desirable tech receives 61 times as many applicants as they have existing jobs, and for good reason. Google seems to be all about coaching. The company’s “CareerGuru” program makes 43 of its senior leaders available for one-on-one, confidential career coaching sessions with other Googlers.  

Engineering employees at all levels can also get advice from “EngAdvisors”, senior engineers at Google who can discuss any number of issues, like work-life balance, conflict resolution, and performance reviews.

NetApp 2012 rank: 3 (2011 rank: 3)

Headquarters: Sunnyvale, Calif., USA

All new employees at data storage provider NetApp participate in the TOAST (“Training On All Special Things”) orientation program, which introduces new arrivals to NetApp’s senior management. The meetings are held every month and are always led by the executive team.  

Microsoft 2012 rank: 4 (2011 rank: 1)

Headquarters: Redmond, Wash., USA

As part of Microsoft’s commitment to promoting women in technology, the company established its DigiGirlz program in 2000. Microsoft hosts a series of DigiGirlz Day events where female high school students meet Microsoft employees and learn about careers in technology. In 2011, some 36 Microsoft locations across the world hosted more than 2,000 girls. Microsoft also holds DigiGirlz High Tech Camps, multi-day programs where participants get hands-on experience with technology during workshops and meet with tech executives.
