I did an interview last Friday afternoon with a recruiter in a staffing company. I wrote her a thanks email once I was back home from her office but I did not receive any response. Today I called her and knew that she already forwarded my resume to the company I applied for. She said the status of the application was pending and let me call her back this Friday.

BTW, I took two tests and filled out a W-4 form in the staffing company during the interview. Now I am wondering why I should fill out the W-4 form before I get a job. I should ask her about it but I forgot. Any idea about the W-4 form issue?

One more thing, when I took the tests, her supervisor also spoke to me for a while, asking my background again and if I am available for an onsite interview with the company I applied for. Is it normal?

Thank you in advance for any input!
