What is taking so long!?!?!

Aw, the wait is the hardest thing. I would follow up. The worse thing they can say is no. Keep applying other places.

Hey All! Just recently had an interview for a job in an ambulatory care office. Well not really recently, about 2 weeks ago. However, I think it went really well, but I havent heard anything back from the employer!! I got in touch with the manager about a week ago to give her my references and she said that should would update me soon because they were wrapping up their interviews with other candidates. She also said that they were introducing a new computer system and needed to get the person they decided to hire in as quickly as possible. Another week went by and still no word, so I called and left the manager a message just to follow up and never heard back. When I left the message however, her voicemail said she was out of the office doing computer training for this new system they adopted at the office. Im wondering if I should just give it up and take the silence as a rejection, or call again?! I dont want to keep calling and getting no response if its a no go. I also am thinking that they may be busy, or something has come up and its just taking them a while to decide. What do you all think? This ever happened to anyone? Should I call again, or just give it up? Comments are always very appreciated!!!
