Mark Zuckerberg didn't just wake up one day as a Billionaire CEO of Facebook (now Meta), he started life as a worker in a completely different way than most people. Before there were boardrooms, IPO's and global impact, the first job that Mark got, was because of his curiosity and ability to create technology. He had a very strong affinity for coding when he was 15 years old and built software to solve real-world issues. 

That time allowed him to build his coding ability and also showed him the attitude he would eventually need to be successful creating applications that people want to use. By being able to understand who Mark Zuckerberg was in the beginning, you highlight how passion, skill and self projects can develop the basis for creating things that change the world.

What was Mark Zuckerberg's First Job?

Zuckerberg started his job journey as a software developer; he developed software while still in high school. Instead of having a part-time position at a fast food or retail store, he wrote software for actual use in real-world applications. 

One of his first software creations was called ZuckNet. The application provided a way for family members and employees in his dad's dental office to communicate quickly and easily with each other by sending messages to one another without having to get up from their desks.

It was the first time he received money for his programming services. In high school, he partnered with another student to develop an intelligent music player called Synapse Media Player, which gathered information about users' music preferences to create customized playlists. 

This work piqued the interest of companies like Microsoft and AOL, which both made him job offers; however, he turned them down so he could attend Harvard University.

 His early programming experience was what set the stage for his future success and development of Facebook.

Facebook was created by Mark Zuckerberg while he was studying at Harvard University in 2004. His dorm room was the birthplace of Facebook, which began as a website to connect Harvard students with each other. 

Originally called TheFacebook, it allowed members to set up profiles, share photos and communicate with fellow students. As its popularity grew, Facebook went beyond just Harvard and expanded to Ivy League universities throughout the U.S., and eventually to all U.S. universities.

 Zuckerberg partnered with some of his roommates and other friends to continually improve upon Facebook and to make it available to as many people as possible, resulting in Zuckerberg dropping out of Harvard so he could devote all his time to building Facebook, which eventually became the world's largest social network.

What did Mark Zuckerberg Study at Harvard?

Mark Zuckerberg attended Harvard University, studying Computer Science and Psychology. He began college in 2002 and gained recognition for his impressive skills with computers as well as learning how people act, interact, and make choices.

In addition to computer science, psychology has informed Zuckerberg's ability to design Facebook based on his understanding of how humans behave what motivates us, how we communicate, and how we make decisions. 

Zuckerberg built several pieces of software while at Harvard, including CourseMatch and Facemash, which used student information to match students with other students based on their interests and preferences.
