- AnthropicMediumSoftware EngineerIdentify the Most Important AI Safety Risk
Tests your ability to analyze AI alignment failure modes—specifically sycophancy and emotional over-reliance—and formulate rigorous evaluation metrics, training mitigations, and product-level guardrails.
Machine LearningHR ScreenAI SafetyRLHFSycophancy - Axq CapitalMediumSoftware EngineerExplain What a Neural Network Is and How It Learns
Explain what a neural network is: how units and layers turn weighted inputs into outputs, why non-linear activations are essential, and how the weights are learned with a loss function, backpropagation, and gradient descent. It tests core machine learning fundamentals, including overfitting and when simpler models are the better choice.
Machine LearningHR Screen - OpenAIMediumSoftware EngineerDesign Restart Strategy for Oracle Solver
This question tests the ability to optimize restart intervals for a randomized algorithm with heavy-tailed runtime distributions, balancing the trade-off between progress and computation waste.
