💡 General Interview Hints

We are fully committed to open-source. Check out https://opensource.jina.ai where you can view all our code, commits, issues, PRs publicly. Hence, when we conduct the interview, we do expect you to have a certain understanding about our products, tech stack and vision.

For the Engineering Role: a Good Pull Request = a Good Cover Letter

Every tech interview involves some kind of code screening. We do it differently at Jina AI. Since we are completely open-source, it is a good way to evaluate your engineering skills based on your first Pull Request to Jina.

If you apply for one of our engineering roles, you can pick one project (JinaDashboardExamples) and work on one bug or new feature. Submit your work via pull request and pass the CICD. Then we will review it.

Note that not only the code, but also the coding style, documentations, commit style, affect our evaluation.

Product and Evangelist Role: Tell us about your understanding

We would like to hear from you about the feedback when using our products. Like really using it, not just looking at our screenshot or documentations. Following the PyPI install instruction or using Docker, either way you need to run the system by yourself. This is the basic requirement for our product related roles.

After playing with our products. We’d like to hear your feedback. What’s your view? What are the good and bad features? How can things be improved? What minimum resources (time & HR) do you need to get this done?
The more you can tell us, the more understanding we have about your skill set.
