问题： Do you have any work experience in this field ?
这是个开放性问题，不用用yes / no 来回答。
你可以说
1) “ I have 4 years experience in staff management”
2) "I have been working as a java developer for 5 years "
3) "I have completed 3 projects, I am sure I can apply my experience to this position"
4) " I have been a product manager"
