I was emailed for a request for a phone interview. I had a phone interview with an HR like employee. The phone interview went well, she asked good questions and I had a positive feeling about it. After that they dropped off the face of the earth. I sent a few follow up emails, and finally got a response that the woman I had been coordinating with no longer worked with the company. After a few exploratory emails I got a response from another person in the company letting me know that they would look into my interview status. To me it sounds like the hiring manager left, and they just let the applicants for the position fall to the wayside.
