DDN interview questions

I had a quick screening call with the talent person, then a 30 minute call with the hiring manager. She started the call by saying it was short for a reason, so we didn't "waste each other's time" in case she didn't like me, and repeatedly told me I would be getting an additional call with her because she did like me, and did want more time to speak with me. She told me the talent guy would get back to me to schedule that soon. Both she and he confirmed the interview went well and I'd be hearing about next steps. Two weeks, two follow-ups, and no updates later, I've been told they selected another candidate with a generic rejection, no feedback, and no explanation as to why I didn't even get a second call, especially after being clear I was going to. Unkind and unprofessional.
