Hi! I actually just watched this movie, as well. "Customer Experience" is not a common phrase, but in the context of the movie, it is meant to imply that they are performing customer service or troubleshooting. In English speaking countries, some job titles may be altered slightly to make them sound more interesting than they are. For example, a clerk at a department store may sometimes be called an "Associate" instead of just "cashier", and so on. "Speed Round" is a reference to a common section of American-style game shows, in which questions are asked quickly, and the contestant is expected to respond without allowing them room to think too deeply about the answer. As far as "customer maintenance for the smaller advertisers", this could mean a few things based on the type of company. My understanding was that the "customer maintenance" portion refers to helping a customer to understand issues regarding billing, placement of advertising, and technical issues. Basically, "customer maintenance" refers just to customer assistance (it's not a common term, but probably just an affectation that was created specifically for this movie). Finally, "smaller advertisers" refers to companies who wish to have advertisements placed on some Circle website or interface, but do not have a large budget to do so (as an example, Microsoft would be a 'larger advertiser', while a small local restaurant would be a 'smaller advertiser'). I hope this helped.
