The CEO is abusive and delusional... Strongly believing in a French-based, top-down and highly hierarchical structure, he will treat you like a god for the first 2 weeks, and then invariably start talking you down and tossing you around unless you happen to agree wholeheartedly with everything he says.
I know of only one person who actually lasted a long time in the Montreal office, and he was a master boot-licker, always nodding his head wholeheartedly at every half-thought decision the CEO was taking on any given day.
