I was having a conversation with a friend about the compensation of an oil trader at a company like Vitol, Trafigura, Glencore etc. compared to one at a company like BP, Shell or P66, and assumed that the compensation was much greater at the trading firms. However after looking at glassdoor the salary figures were around the same for all of the above mentioned.
Of course I'd assume that the bonuses at trading firms are much greater, but I have no way of really confirming that. What exactly is the incentive to go from working at say BP to working at, say Vitol? I've heard the cultures are much different, with the trading firms being much faster paced, but is the salary after bonuses that much greater?
