In an age where company information is commonly available online, it could be embarrassing to stumble through discussion of an investment bank's corporate organization or approach to different market sectors. Such information is usually prominent on a bank's Web site. Reading through recent press releases and media coverage on sites like The Wall Street Journal Online, MarketWatch or the New York Times's Dealbook can make sure you're up-to-date on recent developments. Many banks and financial firms also have a career section on their sites, which provide clues to their approach to hiring.
