Technical practice
How would you structure a small Java full-stack feature so it remains maintainable?
What to coverThe posting prefers Java full-stack skills and calls for clean, maintainable code. Suggested preparation: explain how you would separate responsibilities, keep interfaces clear, and use code reviews to catch defects without adding unnecessary complexity.
When would you use Python for a backend task, and how would you keep the code reliable?
What to coverPython is a preferred skill, and the role includes backend development. Suggested preparation: discuss readable code, input validation, error handling, and tests, while acknowledging that the posting does not specify a Python framework.
How would you evaluate a basic generative AI feature before adding it to an application?
What to coverThe posting lists basic generative AI as a preferred skill but names no particular use case or tool. Suggested preparation: describe a small, clearly scoped example and how you would check output quality, handle unsuitable responses, and protect sensitive inputs.
How would you design an API endpoint for an application feature?
What to coverDeveloping APIs is an explicit responsibility. Suggested preparation: cover the request and response contract, validation, error responses, and tests; explain how you would keep the interface understandable for its consumers.
How would you make an integration resilient to failures in another service?
What to coverThe role includes developing integrations and ensuring reliability. Suggested preparation: discuss timeouts, appropriate retries, error reporting, and how you would avoid treating a failed dependency as a successful request.
What tests would you write before releasing a new backend feature?
What to coverThe posting includes designing, testing, and deploying applications. Suggested preparation: distinguish focused tests of logic from tests of API or integration behaviour, and explain how you would cover normal inputs and failure cases.
What would you check before and after deploying an application change?
What to coverDeployment and application reliability are stated responsibilities. Suggested preparation: describe checks that the change works as intended, how you would detect a regression, and how you would respond if the release caused problems.
How would you investigate a backend defect that you cannot immediately reproduce?
What to coverTroubleshooting and debugging are part of the role. Suggested preparation: explain how you would narrow the failing path, gather relevant evidence, form and test a hypothesis, and verify that the fix addresses the cause.
How would you investigate a slow API as usage increases?
What to coverThe posting calls for performance optimization and scalable applications. Suggested preparation: explain what you would measure first, how you would locate the bottleneck, and how you would weigh an optimization against code complexity.
What security checks would you apply to an API or backend service?
What to coverEnsuring application security is an explicit responsibility, though no security framework is specified. Suggested preparation: discuss validating inputs, controlling access to data, and avoiding disclosure of sensitive information in responses or diagnostics.
Behavioural practice
Tell me about a time you clarified an ambiguous software requirement.
What to coverThe role involves working with business stakeholders, architects, and development teams to understand requirements. Suggested preparation: use a real situation, the questions and actions you took to reach agreement, and the resulting change to the work.
Describe a time a code review changed your approach.
What to coverCode reviews and maintainable code are part of the posting. Suggested preparation: give a real example of the feedback, how you evaluated and acted on it, and the result for code quality or team understanding.
Tell me about a time you helped resolve a difficult defect with others.
What to coverThe role includes troubleshooting, debugging, and collaboration with development teams. Suggested preparation: set out the situation, your specific investigative actions and communication, and how the team verified the outcome.
Describe a time sprint feedback changed how you worked.
What to coverThe posting names sprint planning, stand-ups, and retrospectives. Suggested preparation: choose a real example, explain what you did in response to feedback, and describe the observable result without overstating your contribution.
Tell me about a time you assessed a new technology for a development task.
What to coverThe posting asks developers to stay current with emerging technologies, frameworks, and industry trends. Suggested preparation: describe what prompted the assessment, how you weighed its usefulness against its risks or learning cost, and what decision followed.
