Arowana Consulting interview questions

Mine interview was for Dubai location taken by some Salim or someone I am not sure as he didn't have that manners to tell his name as well. The way interviewer was asking the questions - was really bad manners. He was shouting at me all the time even without any reason, who gave him those rights I don't know? He himself didn't know how to ask a question. He was asking something and expecting answer something else. If we consider that somewhere my answer is wrong then he should just accept it and not shout at me. while giving interview only i want to cut the phone but I didn't because I am not like him manners-less. I can imagine if he is treating to interview candidate like this then how bad he will be shouting and abusing to his subordinates and colleagues.
