请教：这些问题如何回答?

1. Can you tell me what achievements you had in your latest positions?
2. What is the most significant challenge that you have had to overcom in your career to date?

对于ACHIEVEMENTS和CHALLENGE，我感觉好像都是一样的，问实际工作，如何分析，解决问题的能力，是否如我所感觉？ 不知道如何作答。

3.Where do you see your career developing to over the next 3-5 years?
这个是说将来的工作追求和理想吗？ 怕说空，说大了，离实际申请的电力工程师工作太遥远。不知道如何回答是好。
