Corporate culture is the beliefs and behaviors that determine how a company's employees and management interact and handle outside business transactions. Often, corporate culture is implied, not expressly defined, and develops organically over time from the cumulative traits of the people the company hires. A company's culture will be reflected in its dress code, business hours, office setup, employee benefits, turnover, hiring decisions, treatment of clients, client satisfaction and every other aspect of operations. Corporate culture is becoming increasingly important in the war for talent and retention at companies of all types around the world. There are thousands of companies that can be regarded as successful, each with different corporate cultures, and each representing different philosophies of business.
