"work experience" is the type of work you've done in the past. If you haven't started working yet you can say "Right now I'm still a student." or "I'm a recent grad and Ihaven't started working yet." In the second sentence, "recent grad" is short for "recent graduate" and means that you have just finished school.

　　请告诉我你过去的工作经验，工作经验就是你过去所做的工作。如果尚未开始工作，就可以回答“Right now I'm still a student.”（现在我还是个学生。）或者说“I'm a recent grad and I haven't started working yet.”（我刚刚毕业，还没有开始工作。）“recent grad”是“recent graduate”的缩写，意思是刚刚毕业。
