Accenture Scrum Master interview questions

Approached by an Accenture recruiter. Went through three interviews, which were all pleasant experiences. The process was a bit weird because the role was not clearly defined, but decided to keep going through the process to see where it led. The fourth interview was strange. Was then told they didn't want to proceed because I didn't have experience with external clients, which was known from the beginning. Waste of time and energy and money. That last interview and the reason provided left a sour taste in my mouth.
