Homelike Software Developer interview questions

Did a first call with HR. It was a phone call to get to know you and to learn more about the company. Next, I had to do a home assignment. They say it should not take you more than 4 hours, but in reality, it takes at least 3 to 4 days to complete. After submitting the assignment, I was rejected. I asked to HR to provide feedback, and until today I have had no answer.
