[Part 5] Meta Intern Success Series - Writing The Code

- Keep your diffs focused and atomic. Aim for 25-250 lines of code per diff.
- Use stacked diffs: They are core to Meta's code culture. If you're unsure how to break up your work into a diff stack, work with your intern manager to come up with how things should be broken down.
- Make sure that all your diffs have a really good context section. You can have a "Context" section at the top explaining the overall goal of the diff stack (i.e. usually what your intern project is meant to do) and then a "In This Diff" section which explains the specific problem your diff tackles.
- Attach a test plan to show that your code works and to turn the diff review into a high-value artifact. Record a video of you stepping through the flow if possible (this should be easy as many interns work on internal tools) and make sure to cover those edge cases!
- Keep a very close eye on your Phabricator notifications. Your goal is to respond to code review comments quickly (within 30 minutes) and gracefully. **Code review feedback is the main way you grow as a software engineer intern** as the internship's goal is to develop your raw coding ability.
- Land diffs ASAP, so you don't need to deal with rebase hell.

Code review is one of the most common and powerful ways for software engineers to learn. On top of increasing code quality, it builds engineering culture within a team.

Code review can catch coding mistakes and design flaws before the code reaches production

A good code review process is needed to catch bugs, increase maintainability, and guarantee a high velocity future contributors.

Code review ensures high quality software that is maintainable for the lifetime of the code

Meta Platforms, Inc. is an American multinational technology conglomerate based in Menlo Park, California. The company owns 3 of top 4 social networks in the world: Facebook, Instagram, and WhatsApp. More than 3.5 billion people use at least one of the company's core products every month.

An internship is a period of work experience offered by an organization for a limited period of time. In software, a software engineer intern tends to have stronger importance with more competitive pay and real projects to work on.

A successful software engineer intern needs to know how to onboard, work with their manager, write good code, and communicate their projects well.
