Resumable Batch Dataloader with Weighted Sampling
4/5Reported as a Microsoft engineering interview question, this advanced problem asks you to build a unified data loader that pulls weighted batches from multiple iterable sources while supporting complete checkpointing and state restoration. You will need to implement proportional sampling logic alongside robust serialization methods to pause and resume iteration seamlessly. This challenge tests your mastery of custom iterator design, state management, and architectural patterns for data pipelines. The full problem specification and production-grade model solution require a subscription.
