EY Sr. Associate interview questions

I got a call from an external recruiter. Gave the Hirevue assessment and within 2 working days got a call from EY's HR. Cleared 1st and 2nd round of interviews within a week and was informed about another round of interview with case study. However, did not receive any update from HR. When I called her back for an update, she said will let me know. I waited for a month and then dropped an email, only to get an immediate revert with the standard rejection email. Wrote back for feedback, but didn't receive any yet revert.
