Facebook describes its culture through the statement: 'Move Fast. Be Bold. Be Yourself.' On its careers website, the company goes on to describe that 'you'll have the opportunity to work with great people, tackle big challenges and make a real impact, wherever you work--while being your unique, authentic self.'

Facebook also has 5 core values which include:

1) Be Bold. Building great things means taking risks. We have a saying: 'The riskiest thing is to take no risks.' In a world that's changing quickly, you're guaranteed to fail if you don't take any risks.

2) Focus on Impact. To make the most impact, we need to solve the most important problems. We expect Facebook employees to avoid wasting time on minor issues and focus on truly big challenges.

3) Move Fast. We believe that it's better to move fast and make mistakes than to move slowly and miss opportunities. Doing so enables us to build more things and learn faster.

4) Be Open. Informed people make better decisions and make a greater impact -- so we work hard to ensure that everyone at Facebook can access as much information about the company as possible.

5) Build Social Value. At Facebook, we're trying to bring the world closer together -- not just grow our business. Our people focus on creating real value for the world -- every day and in everything they do.

These details can help you to carve out how you can make an impact, as a builder, at Facebook.
