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?
