Forvis Mazars Group Audit - Placement interview questions

The initial telephone interview lasted for over 30 minutes. Asked around 20 questions and all were of behavioral type. We need to research well. I could perform really well as I prepared well for the same but got rejected. Asked Mazars for the interview feedback and during the interview feedback call they said I prepared well and performed well, but I should have said more about Mazars from an industry perspective and my answer to one of the time management questions was brief. I was like "really????"... and asked them if I got rejected only because of these 2 answers as I was confident about this interview. Then that person agreed and said they get a lot of applications for this position and the decision is purely based on the interviewer's judgment. :(
