Domande di colloquio presso Linecraft

They have given me a task to complete on Google meet 1.5 hour call and they have asked me to make the design process for a website.After the call finished they have asked me to make the wireframes and submit it by next day but in the evening I recieved the mail that I got rejected.I still don't understand on what basis they are rejecting me even though the assignment was still not submitted by me.
