IQVIA Senior Machine Learning Engineer interview questions

1) Phone Screen 2) Technical interview with the head of analytics I did not make it past #2. However, after the second interview, I was left with a bad taste in my mouth. The interviewer constantly interrupted me, putting me on the defensive for the whole conversation. I don't think I finished a single sentence without him interrupting me. He was extremely condescending and made me feel as if my prior experience was insignificant. I had no interest in the position by the time my interview ended. Unsurprisingly I did not make it past the second stage. He was trying to weed me out before I even got to speak about my past experiences. And I laugh, because 2 months later I see the position is still open. I wonder why?
