Gallagher Team Manager interview questions

I have received a random call from the HR and she helped me set up an interview. The HR was very polite and supportive in terms of interview. The first round was very nice and took little longer than usual but over all it was a great experience. I moved to another set of interview with the Sr. Managers and it was pathetic. The manager itself was not interested and shooting random questions one by one, without even asking my answer. He was in a hurry and it feels he was not at all interested in taking my interview. The other guy with the Sr. Manager was very nice but he was quiet through out the interview round. I got rejection message from the HR and even she was shocked why I got rejected. She said, the Sr. manager is very weird and even they don't understand what exactly they are looking for this role.
