Veolia interview questions

First round screening with internal HR. Second round virtual panel to discuss a more technical aspect of the job/ my job history. Third round in person to discuss similar topics as round two. The whole process took roughly 4 weeks. Interviewers seemed disinterested throughout the process. Following the in person interview I was told to expect an answer within 1-2 weeks. I never heard back following the interview. Very unprofessional to not follow up.

Simple zoom meeting with two superiors, want well quite friendly and timely, answered questions easily and were very easy going. No complaints about the process or its ease of implementation
