Apply for one position, and use your cover letter to indicate the other positions you would be interested in. As we review your application, we will see which positions are a good match and will approach you about any other potential opportunities.
After a certain period of time, your application will be deleted. If you like, however, we can also save your file for consideration when positions become vacant in the future.
Our consultants are frequently deployed in foreign countries, depending on the project, their area of expertise and linguistic skills. Unfortunately we cannot give a global answer about how much time they spend on domestic vs. international projects.
