crossovercpa on "Regret passing the CPA exam, no firms willing to hire still. Plain Loser?"

I'm full of frustrations now...
I have been working in a very very small public accounting firm for almost three years now. I passed my CPA exam since Nov 2012. I have been searching for mid-size accounting firms since tax season was over, but so far I don't even have a job offer!!! I mean, I will become a CPA within 3 months and I m that incompetence??? This is totally out of my expectation!
I have sent out resumes to almost everywhere, I have 7 agents helping me for job searching as well. The agents were helpful in general because they really brought me some interviews with some firms within 5 days. So far I had 4 interviews but I got rejected in all, which I had no clue completely. I honestly thought I nailed those interviews down, because our conversations were pretty good, I was able to answer their questions firmly. I shared my tax, audit experience with them and they seem impressed! I even sent out thank you letter after the interview and they got back to me saying we would be in touch for second interview next week. But then next week, all I received were "Thank you again for your interest in xxx. While we enjoyed meeting with you and learning more about your background, we will not be moving forward with your candidacy at this time."
This is a disaster for me, I thought passing the exam, having 3 years of experience would help me land a job in one of the firms easily. I'm not asking for high salary anyways. My small accounting firm is closing anytime soon (bosses are 75 years old, retiring, wanna sell the business for extra $$)
I'm lost, I'm panic, I m thinking..was passing the CPA exam was a mistake? because I don't see the benefits so far...
