SAP interview questions

Had two phone screens that went well, and then an in-person interview with one of the managers. I didn't feel put on the spot and I enjoyed the conversation. I was even introduced to some of the current employees. But then I found out a week later that an internal hire was made, even though I had been told that I was the top candidate for the position. I jumped through those interview hoops for no reason. I feel so used that I wouldn't work for this company if they begged.
