On the phone, they may ask you to rank your level from 1 to 10.

NEVER rank yourself at low level, even if it may be true. For Americans, that is a sign of lacking in confidence and initiative assuming those are the major tools for the job. I would recommend you to rank yourself as Advanced user for some softwares and some as Intermediate depending on your experience. And try to remember some advanced functions/jargons for those you say you have advanced skills. Actually, you will be able to learn many skills fast after you get the job! And sometimes although the job requires HIGH level of competency in Access, for example, it may only needs you to know how to run/design simple queries rather than writing codes.

Good luck!

我当时每次人家都问我excel怎么样，hehe,一开始我不敢说我很好，因为之前的老板真的是对这个非常懂，搞得我觉得我自己就跟幼儿园大班那种级别，，，后来发现不说自己很好不行，就大着胆子说了，反正面试的时候他们也不会给我台电脑让我做结果上班了以后发现现在的老板知道的比我少多了
