Crypto.com Software QA Engineer interview questions

I applied from a different platform and got an email from their recruiter few months after to take an offline test which is to design a test using JUnit5 from their trade and candle stick API. I spent 2 days from it and from a QA's perspective I think I've really met the requirement. Code reusability, scalability, architecture are all good. After submitting the test, I never heard a word from them anymore. Such a horrible recruitment process. I could have spent my 2 days somewhere more valuable. It could have been better if they emailed me back about the feedback of the test. I also think they're looking for developers wearing a QA hat for this position.
