2
Coding Screen
3- 2
Type · algorithmic
Imagine you are developing a real-time monitoring system for a critical industrial process (e.g., a chemical plant's temperature regulation). You receive a stream of sensor readings. Write a function to detect and report anomalies, defined as readings that deviate by more than 3 standard deviations from the rolling average of the last 60 readings. Consider efficiency for a high-throughput stream. - 3
Type · algorithmic
A fleet of autonomous guided vehicles (AGVs) operates in a warehouse, moving goods. Each AGV has a unique ID and a current location (x, y coordinates). Given a list of AGV locations and a target destination coordinate, write a function to find the AGV closest to the destination. Optimize for scenarios with a large number of AGVs. - + 1 more questions in this round (sign up to unlock)

System Design
3- 4
Type · system-design
Design a scalable system for Smiths Detection's trace detection portals. These portals need to analyze samples in real-time, communicate results to a central server, and receive configuration updates. Consider data ingestion, processing, storage, and alerting for potential threats. - 5
Type · system-design
Smiths Medical needs a system to remotely monitor and manage a large fleet of infusion pumps in hospitals. Design the backend infrastructure that handles device registration, data collection (e.g., infusion rates, battery status, alerts), remote configuration, and software updates. Discuss challenges like network connectivity in hospitals and data privacy (HIPAA). - + 1 more questions in this round (sign up to unlock)

Onsite Coding
4- 6
Type · coding
You're building a diagnostic tool for a complex industrial machine. The tool needs to interpret error codes, which can be hierarchical and have associated parameters. For example, 'Error 101-A: Valve X failed to close within timeout'. Write a robust parser that can take a raw error string, extract the error code, parameters, and severity, and represent it in a structured format (e.g., a JSON object or a class instance). Handle malformed input gracefully. - 7
Type · coding
Implement a function to simulate the behavior of a simple conveyor belt system used in manufacturing. The belt moves items at a fixed speed. Items are added at one end and removed at the other. The function should track the position of each item over time. Consider potential issues like items overlapping or items falling off if the belt speed or item size is too large relative to the belt length. - + 2 more questions in this round (sign up to unlock)
