  3. Eventually we’re going to Google you. Our clients know how to Google people as well. We pride ourselves on professionalism and high ethical standards. We hire those that practice the same. If you do not have a web presence, then we strongly suggest making one. If you intend to work on building the Internet then we expect you to be a part of it and use it well.
  4. Contributions to show a willingness to help others and show off skills.
  5. Designers: Having a account shows that your peers like your graphical skills.
  6. As a suggestion to applicants that are just getting started, working on projects on (formerly eLance/oDesk) or or show you’re anxious to be challenged and want to be paid for the effort. Start there to build up a body of work. When you have some under your belt that can be shared and you can share what you learned, please apply so we can discuss it.
  7. Full stack development spans many technologies: encompassing server administration, backend development, frontend development, and mobile application engineering. The ideal candidate has years of experience in each individual skill set on real world projects. While it’s known that a Jack of All Trades can master few, if none: the position calls for intermediate experience in each skill.
  8. Finally, we like to know how people keep up with changes in technology. All of us continue to learn from outside sources. We will want to know what sites you read, what industry experts you follow, what conferences you’ve been to or watched online, etc.
