Problem Solving and Communication Approach Questions

Covers the practice of solving technical problems while clearly communicating the thought process. Includes clarifying requirements, asking targeted questions, decomposing problems into subproblems, proposing brute force and optimized approaches, stating assumptions, discussing time and space complexity and trade offs, walking through examples and edge cases, and narrating debugging and recovery when stuck. Also includes collaboration during problem solving, readiness to accept hints, and ability to explain reasoning so others can follow and learn. This area is commonly tested in coding interviews and whiteboard scenarios where the candidate's communication of reasoning and process is as important as the final solution.

During a whiteboard exercise you get stuck. Describe how you would ask for and accept a hint from the interviewer while preserving collaborative tone and demonstrating openness. Give a short script you might use and explain why those words help maintain psychological safety while still driving the problem forward.

Implement, in Python, a streaming online calibration updater that ingests prediction probabilities and labels and updates a simple Platt-scaling logistic calibration model incrementally. Explain assumptions, numerical stability concerns, how you would evaluate calibration quality over time, and how to present calibration drift to stakeholders.

Explain how you would teach the attention mechanism (self-attention) to a junior engineer: include a simple visual example, pseudo-code for the scaled dot-product attention, and describe practical debugging checks you would run to validate attention behavior in a transformer model.

Design a 12-week mentoring program to help junior engineers improve their ability to articulate technical decisions during interviews, design reviews, and code walkthroughs. Include weekly exercises, feedback mechanisms, measurable outcomes, and how you would scale the program across multiple teams.

While pair-programming, your partner confidently asserts an assumption that appears incorrect and would break correctness later. Show how you would diplomatically surface your concern, propose a small test or experiment to validate the assumption, and handle the situation if they insist despite evidence.
