I feel like hiring is so much like gamble. Lot of time, the hiring manager clearly express I should get an offer or a request for next interview the next days.

I feel like hiring is so much like gamble. Lot of time, the hiring manager clearly express I should get an offer or a request for next interview the next days. Only to have radio silent and rejected letter 1-2 week later even me follow up with them. It seems like hiring requires a lot of decisions from multiple people. And they want to be safe, so all have to give a yes.
