Zeiss is a wonderful international company to take part in as an intern. The workforce is quite diverse and coordinating with other international branches is a great experience. The management listens and will do all they can to make sure the job gets done. If you're part of the marketing department you may be asked to take part in setting up some events to give the company exposure such as booths, dinner galas and invite special guests such as doctors from other countries. At times you might get a task that comes out of no where because its an emergency but the environment at Zeiss makes it as less stressful as possible.
