Tests learning agility under delivery pressure, with emphasis on ownership, prioritization, and adapting quickly to unfamiliar technical work.
Tests how you receive criticism, regulate defensiveness, act on feedback, and turn it into measurable improvement.
Tests ownership and communication while debugging a complex software issue under ambiguity and stakeholder pressure.
Tests how you handle ambiguity in a data science project by creating structure, aligning stakeholders, and driving delivery despite unclear requirements.
Explain how `volatile` prevents incorrect compiler optimizations on memory-mapped or asynchronously updated values.
Compare polling and interrupt-driven I/O, including CPU usage, latency, complexity, and when each approach is appropriate in embedded systems.
Explain the role of an Interrupt Service Routine in embedded systems and its significance.
Explain what stack overflow does in embedded systems and how to debug it using stack usage, memory layout, and fault analysis.
