Apple Sr Software Engineer interview questions

Got contacted by an Apple recruiter via Linkedin. He set up a call to talk about the position and my background. He was 30 minutes late for the call. After we had the call, he told me to send him his CV so he can send it to the hiring manager of the open position. When I did it, he replied with a confirmation that he received it and had forwarded to the proper team, and he will get back to me once he hear back from the hiring manager. That was a week ago. I do not understand why the recruiters try to poach engineers and later don't follow up, specially because my Linkedin profile and CV are perfectly in sync. So no room for surprise once I sent my CV over.
