If you are selected for the interview, you will go through the process of general career test, computer coaching interview and formal oral interview. First, the three-hour general career test includes problems on: a) perception, memory and concentration; b) comprehension & problem solving; c) numerical computation; and d) written expression. It is not very difficult test; however, it is a little bit intimidating when you need to figure out complex energy-related tables and figures with such short time. Second, the computer coaching interview means to evaluate your customer service skill and reactive ability in various pre-recorded computer scenarios. The key to do well on this test depends on your ability to talk professionally and to react quickly. Unfortunately, I did not quality for the oral interview based on the result of the coaching interview and had no further comment. But the overall interview process was professional and was good experience for me.
