OneSpan Java Developer interview questions

I applied via a recruiting firm, I got a call from the HR, we've talked about interest and my past experiences. Then, I went to the onsite interview, we've talked about some architectures to technical questions. During the interview, maybe it's me, I felt that the manager that I have spook has some anger issue or the way he talked was very none professional as it should be like in others' past interviews that I did with the other managers. Overall, the technical guy was very nice and the manager was super rude. I was left disappointed.
