EPAM Systems Senior Software Developer interview questions

Telephonic round interview for FE. I gave Walmart Labs interview as well for the same position when I gave an interview for EPAM. EPAM didn't revert but sent a feedback survey of the interview. I got selected by Walmart Labs. I assume either the interviewer doesn't know the subject properly or HR was not okay with the package I was asking. I already had a package that is beyond their senior developer budget. Don't waste candidates' time.
