Sample Hugging Face LLM Engineer questions
A preview of real practice questions from the Wrexa Edge Hugging Face LLM Engineer bank — the same style, phrasing and difficulty you'll face on test day. Full solutions unlock free inside the mock.
HF LLM (50 Q) · ML — Recall
Q1. Recall (sensitivity) is calculated as:
Why: Correct answer: D — TP / (TP + FN) — of actual positives, what fraction were caught. Topic: ML — Recall.
HF LLM (50 Q) · ML — F1
Q2. F1 score is:
Why: Correct answer: A — Harmonic mean of precision and recall: 2 × (P × R) / (P + R). Topic: ML — F1.
HF LLM (50 Q) · ML — AUC-ROC
Q3. AUC-ROC measures:
Why: Correct answer: B — Area under the ROC curve (TPR vs FPR) — probability that a random positive scores higher than a random negative. Topic: ML — AUC-ROC.
HF LLM (50 Q) · ML — Macro Average
Q4. For multi-class classification, "macro average" of F1 means:
Why: Correct answer: C — Compute F1 per class and average equally (treats all classes the same regardless of frequency). Topic: ML — Macro Average.
HF LLM (50 Q) · ML — RMSE
Q5. RMSE (root mean squared error) penalizes:
Why: Correct answer: D — Large errors more than MAE because it squares residuals before averaging. Topic: ML — RMSE.
HF LLM (50 Q) · DL — Activations
Q6. In a deep neural network, the activation function ReLU:
Why: Correct answer: A — f(x) = max(0, x) — fast, helps mitigate vanishing gradients vs sigmoid/tanh. Topic: DL — Activations.
