Pi R Square (India) UI-UX Design Intern interview questions

They asked me to complete designing of almost 4 webpages, including the login & sign up screens. After I finished submitting, they didn't even directly inform me through chat that they rejected me, only on the internships page of Internshala, it was showing I'm not selected, and on asking for feedback, they didn't even reply to me at all. One of the worst interview experiences so far, first of all wasted my valuable time on this careless company that too on Sunday, and secondly they gave no feedback so that I could have understood my mistakes and rectified them for my next interview.
