Walmart Senior Software Engineer Front End interview questions

Got a call from the HR and asked for F2F interview on weekdays. There were two rounds and mostly fundamental questions were asked. The interviewers were nice people, just that couple of times their concepts were not very clear. After the rounds they took me for the lunch and after lunch, they said next 2 rounds will be next week as the interviewers were on leave. Before leaving the HR said my level was far below the desired level, so I can leave for the day :)
