Had three interviews - Screening call, Hiring Manager, HM Peer. I had to do substantial preparation, researching the individuals, and preparing a line of inquiry related to the job description. Everybody was super nice, and it went exceedingly well. I was frankly stunned not to receive an offer, and there was no explanation of why.

Two senior PM's interviewed me in a very congenial style. They had clearly done their homework on me and expected me to have done the same on the job at hand. I enjoyed the hour I had with them and answered all the questions, such as what was the most difficult experience you had in your past jobs and what did you do that improved engineering results. I left believing I was going to come back to meet the engineering team leads, but a week and a half later I was told they went with another candidate and to please keep checking their job boards for another opportunity. That's fair enough, don't you think?
