First step was a Teams call about my experiences and the second step was an assignment. I have perfectly done the assignment and tested for the requirements.

I've sent the assignment in 3 days and they did not answer for 3 weeks!! Afterwards when I asked, they said that I am not selected for further steps because of my assignment. I find this is disrespectful because I've covered all the requirements of the assignment in my answers.

The assignment was a design and I cannot mention a content since it is confidential, but I can upload my own source code to my GitHub account. Go check it yourself to see if it is generic and fast (OR NOT):
