I participated in five rigorous panel interviews and dedicated a significant amount of time to research and preparation. I made it it to the offer stage only to be told that the hiring manager decided to give the open spot on his team to another manager. It is very disheartening to expend so much effort and time to 5 interviews, for the open position to not even be a true open position. Please be more considerate of candidates time and emotional investment in the future. Our time is valuable too.
