Legal One Senior PHP Developer interview questions

It was the worst experience I have ever had with a company. They sent a coding task to complete. After I completed the task that took entire 2 days and sent it back, they rejected me after 3 days, and when I asked them to give me feedback about my code they sent me a template email that said "It lacked something on the points" without any details. I guess they did not even check my code carefully and I think I wasted my time applying for this company.
