call 獵頭, and talk ....

There are many different kind of head hunters, be sure use the one who has good relation with the client company.

Call your agent and ask:

Steve,
I saw the same job publish on Microhoo's web site again, does that means they denied my resume?

How good do you know the hiring manager?
How many people have you place in Microhoo?
Would you please let me know if you get any updated information?

From the conversation, you will know how strong relation the guy have with the client company.
Thanks!
