Cisco Support Manager interview questions

4 interviews, HR, Hiring Manager, Top Director and overseas area manager. Good interviews, nice people, very in sync with my profile and experience but no feedback in the end of the process. The most strange is that some other people I know that never been interviewed had been contact, by staffing email, to thanks for the participation, but I had participate in 4 interviews and the last one was more then a month ago, but I have never received any feedback and the job position is closed in the carrers website.
