Global Excel Management interview questions

Went all the way to the second interview stage. The HR person pretended to be friendly but when I asked questions about the job, she got more strange and cut the interview short. Later she sent me an email to "thank me" for taking the time but they were moving on with other candidates. How can you disqualify someone because they were interested in learning more about the position - since not all details were given in the job add? - Very strange experience. First interview was done electronically through an app that you get to record yourself and send them a video of you answering the questions they want answered.
