While I was working at Microsoft as a vendor, a PM with whom I'd worked approached me to ask if I might be interested in applying for a Senior PM position he would be hiring and for which he thought I would be a good fit.
I applied online and he indicated to HR that he wanted me in the candidate pool. They scheduled a day of interviews in the form of Lync meetings, which I found tricky because I didn't have the benefit of meeting with the interviewers face-to-face.
I made it through the full day of interviews but didn't hear from them for weeks. I pinged my original contact a couple of weeks later and he let me know that the individual members of team with which I'd interviewed couldn't agree on the qualities they were looking for or what they hoped the person in the position would actually do so they couldn't agree that I was the person for the job. Ultimately he let me know that half the team wanted me but the other half were undecided. They opted not to hire the position at all until they could agree on the specifics about the role. I believe they still haven't hired.
