Protera interview questions

I got a call for the interview from the HR for the screening process However my resume got shortlisted and interview was schedule on 21st June 2023. Lady took the first round of interview she just asked about the job role in the current company and the interview was done. After 8 days I got an Email from the HR saying that I have not selected. I am still confuse Employer didn't asked me more question in regards to technical and she rejected me. This is one of the worst process of taking interview and warping up within 10 minutes.

I rejected the interview because in the initial screening process they requested company proprietary work product be submitted for evaluation. While I have no problem discussing my background and experience, I found this request to be unethical and unprofessional and would not associate with such a company.
