Choosing between Chinese and German for a foreign language requirement in a mechanical engineering program involves weighing career prospects and language learning challenges. Mandarin is highlighted as a valuable asset due to China's rapid economic growth and increasing demand for engineers, potentially broadening job opportunities. However, achieving fluency in Mandarin requires a significant investment of time—approximately 2400 hours for native English speakers—compared to around 800 hours for German. While learning Mandarin can demonstrate cultural awareness, German may be more practical for business use and easier to learn. Additionally, some engineering programs may exempt students from foreign language requirements, which could influence the decision.
