Prisma IT Senior Java Developer interview questions

I found their advertisement on Linkedin and applied for the Java developer role. After some interviews about my experiences, what program and language I'm using, and some other technical questions, I have participated in a challenging test, I have hired at Prisma.

I passed the first and second(including technical) interview processes. The third phase: They send me a coding challenge (sneaksAndLadders game for both backend and frontend) that needs to be done in 24 hours, I completed and sent it in 24 hours. I spent minimum 10 hours for the whole interview process. My game was working, with all functionality. BUT THEY DID NOT GIVE ME ANY POSITIVE OR NEGATIVE FEEDBACK AND DIDN'T RESPOND TO MY MAIL. I wish they would send me a at least negative response mail because I spent 10 hours.
