EY Senior Associate interview questions

Fairly easy questions, team seemed nice, recieved a verbal offer from the Partner in the final round. Followed by rejection email with no explanation. I even reached out to the recruiter after for feedback but got ghosted. Extremely unprofessional.

3 round interview- first round with HR, second round with the partners, and third round with other senior members of the team. No technical assessment, although lots of CV questions.
