the interview has 3rounds in total. 1. the HR had the preliminary interview with me and gave me the assignment to complete, I'd say it's not a test, but more like an employee's regular work. 2. I delivered a presentation to 4-5people, and they asked questions about my work. The manager introduced the company business and team in the end. After the 2nd interview, they ghosted me and didn't give me any feedback, apparently, it's a rejection.
