Enfabrica interview questions

I went through 2 rounds. First round was very engaging. Was asked about overall experience, what I did in one of the previous companies. Brief discussion on developing test bench. 2nd round was more like an enquiry round rather than an interview, asked about my work experience and how I did the projects. He said yes to everything I said and finally was not given any nod. As usual HR ghosted until you ask them back. People nodding to everything and then rejecting without a proper reason looks unprofessional.
