GitHub Infrastructure Engineer Questionnaire

Thanks again for applying to the Infrastructure Engineer job at GitHub! The purpose of this gist is to get a better sense of your technical skills and overall communication style. Take as much time as you need to answer these questions.

Section 1

Engineers at GitHub communicate primarily in written form, via GitHub Issues and Pull Requests. We expect our engineers to communicate clearly and effectively; they should be able to concisely express both their ideas as well as complex technological concepts.

Please answer the following questions in as much detail as you feel comfortable with. The questions are purposefully open-ended, and we hope you take the opportunity to show us your familiarity with various technologies, tools, and techniques. Limit each answer to half a page if possible; walls of text are not required, and you'll have a chance to discuss your answers in further detail during a phone interview if we move forward in the process. Finally, feel
