About the interview process
Once we’ve received your resume, we’ll assess whether your skills and experience align well with the challenges we’re working on at CityBase. If it looks like a good fit, we’ll arrange a call with someone for the recruitment team to talk about how your goals and experience align with CityBase and with one of our senior Elixir developers. Through your discussion with our dev team you with an opportunity to ask us questions about the company, work environment, projects, teams and anything else about CityBase that piques your curiosity. We’ll also cover some basic technical questions to verify your experience.
We next offer two paths forward.
If you have made open source code contributions that you feel are a good representation of your skills and experience then we’ll ask you to send us some repos, PRs or specific commits that we can review. This path, our preferred method of assessing your skills, recognizes that your time is finite and valuable, that open source is an integral part of our stack at CityBase and the value of open source software to society.
If you have not yet had the opportunity to contribute to open source, we’ll be happy to send you a programming task that will take a couple of hours to complete and give you an opportunity to demonstrate your knowledge in the programming language in which you are most confident. It need not be Elixir as we understand that not everyone excited about Elixir has had an opportunity to work professionally in the language.
In either case we’ll take 2 to 3 days to assess your code and get back to you about next steps.
The third stage is a series of back to back video or in-person interviews, primarily with engineers and product managers, designed to give you the best sense of the culture and to challenge your skills in designing complex systems, comprehending and refactoring code, communication and collaboration.
Our assessments are NOT algorithmic whiteboard exercises. We’re interested in seeing how you solve problems and communicate your thinking in a more realistic environment as we feel that gives us the most accurate picture of your skills.
Typically we respond to applicants within 8 business hours of receiving their application to organize an initial discussion at a time convenient to them within 5 business days.
We try to organize the remaining stages quickly after that.
After each stage we endeavor to respond to the applicant within 8 business hours about next steps. The code review portion of the process can take slightly longer, but we’re committed to getting back to you within 3 days for that portion.
