after interview

hi all,  I applied for a full time job in IB (top US ib) through recruiting website (efinancialcareers) rather than campus on Jan. 23. After my application, I had two phone interviews on Jan. 25 and Feb. 4 respectively. I got good feeling after the interviews, however, I haven't received any response from them after the 2nd interview. I sent mail to their coordinator two days ago, while they still didn't reply me. I am in very bad mood now and start to concern I am out from the shortlist. May I ask anyone meets this kind of situation? should I call their coordinator or give up expecting? many thanks for your reply in advance.
