How do you define a culture of a company?

From outside the organization the logo and caption of the organization, the vision and mission statement, the branding and advertising of the organization tells us about the culture of the organization. And from inside the organization the hierarchy, delegating process, sharing of the information with inside and outside people, seminars and events conducted by the organization, infrastructure, facilities given to different employees as per their positions, interactions among the employees.the people involved in key decisions tells us about the culture of the organization. And from the above observations you can define the organization culture.
