Abnormal AI Technical Support Engineer interview questions

Pathetic interview process, The first round was with the HR and it included some basic questions related to previous experiences and some customer situations. It was cleared. The second round happened with the hiring manager and he also put the same questions and I answered them with similar answers. Generic career and customer situation questions. Then I received an automated email that I am not selected, just like that. Without any feedback. One of the worst interviews I have ever had.
