It was a Zoom interview. The interviewer pulled off a flowchart from their existing project and asked me to write test cases. Though I mentioned all possible use cases, covering over thirty functional and non-functional test cases, he was not happy with the answer. Also, he stopped me in the middle and said that this was not working. That was not what he was expecting, and I should go study, come back, and try again in Rapido or any other company. He rejected me right to my face in less than thirty minutes. Also, when I asked what the test cases were that he was expecting me to answer, he told me the exact same answers. It was very rude and unprofessional.

Design test case.
