job offer

[pedspnp]

I need some feed back I interviewed for a NP position, was told the offer was contingent on the interview with the MD who is coming from out of state had the phone conf this am, the chief financial officer stated they would get back with my recruiter this afternoon with an offer, I called the recruiter this afternoon she said they had the offer together that every one was in agreement about me that I would be a good fit but were waiting for the CEO to approve it and they could not get ahold of him so now I am wondering if they have changed their minds advice please
