Headquarters Cannabis interview questions

I didn't even had an interview, they sent me 3 tests that I've completed, one of them took about 4 hours, they told me that "If you would like us to provide you with specific feedback, please reach out to us, and we will do our best to get back to you as soon as possible." I've reached out and follow to them by email for a month after the test was done, WITHOUT any response, the company only made lose time to any future prospect.
