BioSearch Recruiting interview questions

Two phone interviews. First one was with the company recruiter. This went well, they told me they would send my info to the CEO. Second call was with the CEO. This call went well. He made it seem like the job was mine but he wanted me to sleep on it. He told me if this is something I wanted to do then I should call the recruiter I spoke to first and tell them I accept. The next morning I called the recruiter back. They had no idea what I was talking about . They said they hadn't even connected with him. They told me they will call him and call me back. I never heard from them again. This was a Very strange experience.
