First Round - Coding Round 1. Mirror binary tree at alternate level 2. Check if Knight can reach from given source to destination

A system design question which has requirements already laid out. The interviewer listens ,asks very basic questions just on the lines of shared requirements . No in depth questions ,no counter arguments and after few days received a standard rejection email. If interviewer himself is sort of inexperienced or not much interested in discussing then best of luck ,be ready with their mugged up version of answers or look for better companies
