I applied through a recruiter, and was told there was no public posting because they were planning on firing the current employee. I had a phone interview and two in-person interviews. The interviews themselves were straightforward. I was then told they'd be sending me an offer.
I didn't hear anything for a week, then was told that they'd decided to give the existing employee another chance. A few weeks later I was told that they'd decided to move on from them and wanted to make me an offer. They later admitted that the employee had actually unexpectedly quit.
I got a lowball offer with promises of how amazing the company culture is. Needless to say, my interest in working for the company no longer existed.
