Technical practice
How would you define object detection and defect detection for a manual assembly inspection task?
What to coverThe project focuses on AI algorithms for both object and defect detection. Suggested preparation: explain how you would define the target outputs and distinguish a missing or misplaced object from a defect, while stating any assumptions about the inspection task.
How would you build and split an image dataset for this research?
What to coverThe role involves developing detection algorithms, but the posting does not specify a dataset. Suggested preparation: discuss annotation consistency, coverage of normal and defective examples, and splits that avoid leakage between training and evaluation.
How would you choose an initial detection approach?
What to coverThe posting calls for research and development of AI technologies for object and defect detection. Suggested preparation: compare a simple baseline with a deep-learning approach, considering data availability, detection accuracy, computational cost and ease of integration.
How would you evaluate whether a defect detector is useful?
What to coverDefect detection is a stated project goal; no success metric is specified. Suggested preparation: explain precision and recall, the consequences of missed defects versus false alarms, and how you would examine performance across different defect types.
How would you investigate a detector that performs well in testing but poorly on new assembly images?
What to coverThe role covers algorithm development and system integration. Suggested preparation: check for changes in lighting, viewpoint or image quality, as well as annotation issues and train-test leakage, before deciding whether to adjust data, imaging or the model.
What imaging and computing equipment considerations matter for an inspection system?
What to coverThe posting asks for knowledge of imaging and computing devices and equipment. Suggested preparation: discuss how image resolution, lighting, camera placement, processing capacity and maintenance can affect detection reliability, without assuming particular equipment is used.
How would you organize a detection experiment in PyTorch or TensorFlow?
What to coverThe posting names PyTorch and TensorFlow among relevant deep-learning frameworks. Suggested preparation: explain a reproducible workflow for data loading, training, validation, checkpointing and comparison against a baseline; do not assume the project mandates one framework.
How would you use Python and C when moving a detection algorithm into a system?
What to coverThe role calls for proficiency in C and Python and integration of developed algorithms. Suggested preparation: describe possible language boundaries, data exchange and testing considerations, while making clear that the posting does not prescribe an architecture.
How would you test an integrated detection system beyond model accuracy?
What to coverSystem integration is an explicit responsibility. Suggested preparation: describe checks for image-input handling, output consistency, processing time and failure cases, and explain how you would distinguish model faults from integration faults.
How would you present research results in a project report?
What to coverThe role includes preparing project reports, and prior publication experience is preferred. Suggested preparation: outline how to document methods, datasets, metrics, limitations and next experiments so that results can be reviewed and reproduced.
Behavioural practice
Tell me about a time you advanced research while working independently and with a team.
What to coverThe posting calls for the ability to work both independently and in a team. Suggested preparation: give a real situation, your own actions and the result, distinguishing independent decisions from contributions made with others.
Describe a time you guided a student or helped someone learn a technical concept.
What to coverMentorship and academic guidance to students are stated responsibilities. Suggested preparation: use a real example to explain the learner's need, how you adapted your guidance and what resulted; if you have not mentored a student, identify the example's different context.
Tell me about a time you coordinated equipment needs within a budget or other resource constraint.
What to coverThe role includes overseeing a project budget and coordinating equipment procurement and maintenance. Suggested preparation: describe the situation, how you prioritized needs and coordinated action, and the outcome, without claiming experience you do not have.
Describe a time you managed competing technical tasks and reporting deadlines.
What to coverThe posting names organizational and time-management skills and responsibility for project reports. Suggested preparation: give a real situation, your prioritization and communication actions, and the result, including any trade-offs you made.
Tell me about a time you communicated a technical finding or limitation to collaborators.
What to coverStrong communication skills are required, and the role includes compiling project reports. Suggested preparation: explain the audience and situation, how you made the finding and its uncertainty clear, and what action or decision followed.
