Sage interview questions

Particularly unpleasant candidate experience (France). Deplorable organization: at 6pm, receptionist is already left, security officer manages visitors reception. In my case I spent 20 minutes waiting for the interviewer, as security officer didn’t have a right number and was not able to reach out the interviewer. The recruiter was out and his number did not answer. I also sent a mail to the interviewer (People Business Partner) and the recruiter in order to inform them that I was here. Unfortunately it didn’t help either. 20 minutes later I got a call from the People Business Partner blaming me for being late. During the interview the People Business Partner first answered calls of her children and discussed «choir classes issues» in front of me, after she got another call and left the meeting room in the middle of the conversation. I did not receive any apology for the interview organization/ inconvenience during the interview and never got any feedback.
