Harmonic Fund Services interview questions

During the 1.5-hour interview, the employer omitted discussing the nature of the company and neglected to provide an introduction to the organization. Additionally, I did not have the opportunity to ask any questions at the conclusion of the interview. Overall, I found the handling of the interview to be lacking in professionalism.

The first round of the interview was a test assignment to create functional and logical test cases for the completely not familiar product within 2 hours. After 4 days did not receive any response and email to follow up just to be rejected. I never understand the interviewer's expectation from the candidates to be able to build comprehensive test cases when it takes them days to create by their own team.
