Google SWE-3 to Senior SWE: Roles, Responsibilties and Salaries

Google LLC is a multinational technology company based in the United States. It focuses on Internet-related services and products, such as online advertising technologies, a search engine, cloud computing, software, and hardware. Google is part of the Big Five companies in the U.S. information technology industry, along with Amazon, Facebook (now Meta), Apple, and Microsoft.

Google was founded in September 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University in California. Together, they created a search engine that listed results according to the popularity of the pages, calling this new technology PageRank. They incorporated the company as Google Inc. on September 4, 1998, in a friend’s garage in Menlo Park, California. Google’s rapid growth since its incorporation has led to the development of various products, acquisitions, and partnerships beyond Google’s core search engine.

Google’s mission statement is “to organize the world’s information and make it universally accessible and useful.” Its unofficial slogan was “Don’t be evil,” but in October 2015, this was replaced in the Alphabet Inc. corporate code of conduct by the phrase “Do the right thing.” Nevertheless, the original phrase is still kept in Google’s own code of conduct. Google’s culture is known for its focus on innovation and its distinct work environment.
