Walmart interview experience

I recently attended Walmart interview for ABAP support position. I have total 9 years of experience which includes Fiori, ui5, ABAP, RAP, BW.

First round went pretty well and they didn’t asked any coding questions and got positive feedback from interviewer during the interview. But surprisingly, I got negative feedback and not selected for second round. I am not able to understand that what might be the reason that I am not selected ?

Any comments!?
