+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at [INSERT EMAIL ADDRESS]. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Contributing Guidelines
+
+Thanks for contributing! Please adhere to the [Contributor Code of Conduct](/CODE_OF_CONDUCT.md).
+
+Please send a pull request if you have any [additions, updates](#additions-or-updates) or [removals](#removals). Pull requests will be accepted if:
+
+## Additions or updates
+1. The pull request adheres to the repository's
+    [Code of Conduct](/CODE_OF_CONDUCT.md)
+1. The company fits the criteria
+1. You add the company in alphabetical order in the list
+1. You submit the company with a website
+1. You submit the company with a location
+1. You submit the company with a brief description of the interview process
+
+## Removals
+1. The pull request adheres to the repository's
+    [Code of Conduct](/CODE_OF_CONDUCT.md)
+1. Read the following:
+    - The use of the term "whiteboards" is metaphorical - if the interview calls for CS knowledge as a **requirement** (i.e. you require the knowledge to do your job), then it is OK
+    - Screening questions that involve a CS question/brainteaser/puzzle are considered to be disqualifiers from being included in this list
+1. Explain why the company does not fit the criteria
+1. The PR will be merged assuming the guidelines are followed
+1. The person who added the company will be given a chance to respond and add the company back if it does indeed **require** CS knowledge
