Thanks, 如月!
Then I got an idea---why don't I try to search my company by name to see whether they have BI positions? (It is a large global one)
Surprise--They do have BI positions, but it is cognos in Illinois.. I would suggest classmates to try, maybe they will train you.
Now I got a good idea on experience.....
Suggestion: if you stuck on experience problem like me, why don't search your company's career website by keyword BI or IT, you might get it.
