In late July, the Seattle Post-Intelligencer reported that Microsoft had added 10,000 new employees in fiscal 2006. So what are all those new folks doing, exactly? The Seattle PI does some analysis, based on Microsoft’s annual 10K filing. About 4,000 went to product research and development; 3,000 to sales and marketing; 1,000 to product support and consulting; and 2,000 to general and administration. There’s no additional break-down data available. But many company watchers believe Microsoft’s Platform and Services unit, home of the Windows Live family of products, is absorbing most of the new hires.
