The following 9 questions are to test your conceptual understanding of computer science. There are no standard answers to these questions; and there is no score system to grade your performance. So don’t worry about the score. Feel free to express your technical opinions and creativity, as you deem appropriate. Through this set of Q&A, we mainly intend to know more about your thinking pattern and ability to conceptualize and to reason.
The test will be 45~60 minutes. Please try to answer in English and type up your answers in MS Word. Please be as concise and clear in your answers as possible. If you have difficulty expressing in English at times, you can use Chinese to substitute.
