What is corporate culture? Corporate culture describes the atmosphere and mix of people who work at a particular company. The corporate culture at a high achieving accounting firm may be strict and formal. Working hours might be longer than usual, the employees may comprise of mostly workaholics, and the atmosphere will probably feel intense. On the other hand, a start-up social media company may have a more relaxed corporate culture, with unorthodox working hours, casual attire, and usually a younger staff.
