management activities. However, manufacturing companies still tend to opt for engineers more frequently (40.7 percent) than service companies (13.8 percent). We also found that 69.8 percent of the vacancies do not require advanced knowledge of English, which could be a reflection of the low degree of integration in global supply chains by many Brazilian companies. Considering that the study represented a "snapshot" of a particular moment, it is not possible to know if the demand for English-speaking professionals is increasing, and at what pace. Nevertheless, 25.1 percent of companies require good knowledge of English, or value candidates that are familiar with a second foreign language. Both manufacturing and service companies are hiring professionals in the area of operations management with the expectation that they will be engaged with leadership activities in the organization. This was expected, considering that all ads we analyzed were for positions that required college education. For about 25 percent of the listed operations management topics, a statistically significant difference was observed in the relative frequency they were demanded in the advertisements of manufacturing and services companies. This is in accordance with our expectations: manufacturing companies have shown more concern with production and process management, and with systems that support such activities. They are also more interested than service companies are in managing quality, standardizing processes and measuring work improvement. As they deal with inventories, they are also more concerned with the implementation of lean production. Service companies, in turn, have shown greater interest in logistics and distribution practices, as well as in project management. As service operations are increasingly in demand, it is reasonable for managers and the schools that provide their formal education-to reflect on the emphasis they give to the operations management topics that are more important to service companies. The need for training in these areas will continue to grow together with the trend of an increasing percentage of work migrating to the service sector. Despite the revealing results, this study presents some limitations that reduce the power of its conclusions. There is some degree of subjectivity in the interpretation of the contents
