Technical practice
How would you structure Python code for a maintainable AI-driven application?
What to coverSuggested preparation: Explain how you would separate application logic from AI-component integration and keep interfaces clear. Discuss readable code, documentation, and tests that make changes safer.
How would you investigate slow Python code in a production application?
What to coverSuggested preparation: Describe how you would identify the bottleneck before changing code, then evaluate improvements against readability and correctness. Distinguish Python-side work from time spent in an integrated AI component.
How would you integrate an AI component into an existing software product?
What to coverSuggested preparation: Cover input and output contracts, handling failures, and coordination with teams responsible for the surrounding product. Explain how you would validate the integration before release.
How would you test an AI-driven application when outputs may vary?
What to coverSuggested preparation: Discuss repeatable checks for conventional software behaviour alongside evaluation of the AI-dependent behaviour. Explain how you would choose useful test cases and decide whether a change is acceptable.
How would you debug an AI-driven application that produces an unexpected result?
What to coverSuggested preparation: Walk through isolating whether the issue originates in inputs, Python application logic, the AI component, or their interaction. Describe what evidence you would collect and how you would verify a fix.
Where should AI integration checks fit in the software development lifecycle?
What to coverSuggested preparation: Describe checks from development through validation, release, and maintenance, including how quality and compliance concerns would be reviewed. Keep the discussion at the level of sound engineering practice rather than assuming a specific company policy.
How would you use AI within the engineering lifecycle without compromising quality?
What to coverSuggested preparation: The role calls for AI as a core part of how software is built; discuss a plausible development use and how you would verify the resulting work. Address the trade-off between speed and the need for review, testing, and documentation.
How would you monitor and improve the reliability of an AI-driven application in production?
What to coverSuggested preparation: Explain what signals would help you detect failures or degraded performance and how you would investigate them. Discuss how monitoring findings could guide a measured improvement.
How would you support deployment and maintenance of an AI-driven application?
What to coverSuggested preparation: Describe release validation, diagnosing problems after deployment, and maintaining the application as components change. Explain how you would limit risk while making a necessary update.
How would you use version control in a collaborative change to an AI-driven product?
What to coverSuggested preparation: Discuss how you would keep a change understandable, coordinate review, and resolve conflicting edits. Relate the workflow to maintaining tested, documented code.
Behavioural practice
Tell me about a time you worked across teams to integrate a software component.
What to coverSuggested practice: Use a real situation, your actions to align interfaces or goals, and the result. Highlight how you handled differing priorities without claiming experience you do not have.
Describe a time you independently resolved a difficult software problem.
What to coverSuggested practice: Explain the situation, the evidence you gathered, the solution you contributed, and the outcome. Show when you sought input while retaining ownership of your work.
Tell me about a time you helped a junior colleague adopt a development practice.
What to coverSuggested practice: Give the situation, what guidance you provided, and the observable result. Focus on how you made the practice understandable rather than simply taking over the task.
Describe a team discussion where you proposed a solution and incorporated feedback.
What to coverSuggested practice: Set out the problem, your contribution, how you responded to other views, and the decision or result. This relates to the posting's expectation of active participation in team discussions.
Tell me about a change you made to improve software quality or the way it was built.
What to coverSuggested practice: Describe the initial problem, the action you took, and evidence of the result. Explain any trade-off between faster delivery and maintaining quality.
