Distributed Training Strategies

Problem Overview

Explain the major distributed training approaches used for large language models. Specifically: (1) Describe what distributed training strategies exist (e.g., data parallelism, model parallelism, tensor parallelism, pipeline parallelism). (2) Detail how Tensor Parallelism (TP) operates mechanically…

• 3 candidate-reported follow-ups — the exact probes interviewers asked, with the trigger for each
• The rest of the problem statement — full requirements, constraints, and edge cases
• Approach and trade-offs — what passing candidates did, and the mistakes that sink people
