Walmart Global Tech Senior Staff Software Engineer interview questions

Worst panel, don’t waste time here, applied for Walmart emerging technology converse team, Sunnyvale CA location . Hiring mgr and hr were good. But panel member were not good . And hackerrank link is always broken . This interview had 2 coding round , the last coding round had 2 LC hard questions I solved both of them in 1hr , executed the code but still got rejected when asked for feedback HR said panel said I did not execute it, lol , complete waste of my time here. Either they had another candidate or they want to do false interviews, total waste of my time . When I gave feedback to hr he said will review with HM , but no response , I will never apply for Walmart anymore nor recommend anyone , Questions : design Instagram , design ticket booking system , design distributed system and api , design cache framework , Print all k distance node from target , print all permutations in array , right side view of tree.
