回复：最近有点身心疲惫的感觉

Man, do not be too hard on yourself. New post for the position does not mean you were un-qualified. Some company they paid to do the post for a period of time, they will do it anyway. Not for the purpose of the position, it is also promoting the company itself. Of course, if they believe they see a better fit than you, they will take it ... anyway, I think your conclusion may not be the truth.

Take care.
