Technical practice
How would you make a website responsive and check browser compatibility?
What to coverPreparation suggestion: Explain how HTML5, CSS3 and JavaScript support layouts that adapt to different screen sizes. Describe how you would check the result in different browsers and fix a layout or interaction that behaves differently.
How would you build an interactive AI-enabled interface with React?
What to coverPreparation suggestion: Describe a simple component structure and how you would manage user input, loading, results and errors. Explain how those states affect the user experience while a response is pending.
How would a web application communicate with an external AI service through an API?
What to coverPreparation suggestion: Walk through a request and response, including input validation and handling a failed call. As an implementation consideration, explain where you would keep service credentials rather than exposing them in front-end code.
How would you compare AI services for a conversational or content-generation feature?
What to coverPreparation suggestion: Use the posting's examples—OpenAI, Google Gemini and Hugging Face—to discuss fit for the task, integration effort and response quality. Frame your comparison as an evaluation approach, not as a claim that one service is used for a particular DigitalXNode product.
How would you improve a prompt that gives inconsistent chatbot responses?
What to coverPreparation suggestion: Discuss clarifying the task, providing relevant context and specifying the desired output. Explain how you would test revised prompts against representative inputs and compare the responses.
When might LangChain, TensorFlow or PyTorch be useful in an AI web application?
What to coverPreparation suggestion: Distinguish an application-building library such as LangChain from machine-learning frameworks such as TensorFlow and PyTorch. Explain that the choice depends on whether the task involves connecting AI capabilities to an application or working directly with models.
How would you trace data through a simple full-stack AI web feature?
What to coverPreparation suggestion: Describe the path from a React interface through a back-end API to an external service, then back to the user. Node.js, REST APIs and PostgreSQL appear in the posting's technology list; if you use them in your example, explain each one's possible role without assuming a required architecture.
What would you check before helping deploy an AI web application to a cloud platform?
What to coverPreparation suggestion: Cover application configuration, access to external services, basic post-release checks and how to identify a deployment error. The role mentions learning hosting and release workflows on AWS, Google Cloud or Azure, so keep the explanation at an intern-appropriate level.
How would you test and debug a feature that stops displaying AI responses?
What to coverPreparation suggestion: Explain how you would reproduce the issue and inspect the interface, application logs and API response to narrow down the cause. Describe a focused fix and a follow-up test that checks both the failure and the normal path.
How would you keep a small web feature maintainable for other developers?
What to coverPreparation suggestion: Discuss clear component or function boundaries, readable naming and documentation of how the feature connects to an API. Source-code management is listed as preferred, so you could also explain how a focused change would be easy for teammates to review.
Behavioural practice
Tell me about a time you coordinated with others to complete a technical task.
What to coverPreparation suggestion: Use a real example, including the situation, your actions to clarify responsibilities or communicate progress, and the result. Focus on collaboration rather than presenting the work as a solo achievement.
Describe a time you investigated a bug or unexpected result.
What to coverPreparation suggestion: State the situation and how you narrowed down the problem, tested a change or sought help. Finish with the result and what you learned about troubleshooting.
Tell me about a time you learned an unfamiliar development tool or concept for a task.
What to coverPreparation suggestion: Explain the situation, the steps you took to learn and apply it, and the outcome. An example involving web development or AI is relevant if you have one, but do not invent experience with a named tool.
Describe a time a project requirement changed while you were working on it.
What to coverPreparation suggestion: Give the situation, how you confirmed the new expectation and adjusted your work, and the result. Highlight communication and adaptability, both of which the posting calls for.
Tell me about a time you documented work so someone else could continue it.
What to coverPreparation suggestion: Describe the situation, what notes or technical details you recorded, and how you checked they were useful. End with the result for the other person or the project, consistent with the role's documentation and team-update duties.
