Got a interview call (onsite) followed by a test (not a speed test) which asked to develop a very sophisticated lottery system keeping in mind all the constraints. The description seemed very easy but the actual implementation had lot of things to be considered. The interview panel was friendly.

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.
