Most Common Machine Learning Interview Questions (with Answers)
A large number of AI systems are constructed on machine learning, which is also an important point of exchange in almost all AI interviews. You will gain important credibility in this section whether you are applying as a data scientist, machine learning (ML) engineer, or artificial intelligence (AI) product manager.
1. Supervised, Unsupervised & Reinforcement Learning
You will be asked to describe how these three important learning paradigms differ from one another. Here’s how to give a simple, assured response:
“What’s the difference between supervised, unsupervised, and reinforcement learning?”
Answer:
- Supervised Learning uses labeled data. It learns a function from inputs to outputs. Think: classification or regression problems (e.g., spam detection).
- Unsupervised Learning deals with unlabeled data. It finds hidden patterns or groupings. Think: clustering (e.g., customer segmentation).
- Reinforcement Learning is about learning through trial and error. An agent interacts with an environment, gets rewards, and learns a policy. Think: robotics, gaming, self-driving cars.
Tip: Give real-world examples for each to show practical understanding.
2. Common ML Algorithms (SVM, Decision Trees, KNN, Random Forest)
Expect direct questions like:
“Which machine learning algorithm would you choose for a classification task and why?”
Be ready to talk about:
- SVM (Support Vector Machines): Good for high-dimensional data.
- Decision Trees: Easy to interpret, good for explainability.
- KNN (K-Nearest Neighbors): Simple, lazy learning algorithm for small datasets.
- Random Forest: Ensemble of trees, great for reducing overfitting and improving accuracy.
Pro Tip: Mention trade-offs. For example, Random Forests are accurate but less interpretable than single decision trees.
3. Model Evaluation (Precision, Recall, F1 Score, Confusion Matrix)
This is where measurements and theory come into contact. Your ability to select the correct measure for the correct issue is what interviewers are looking for.
“How do you evaluate a machine learning model?”
Key points to mention:
- Accuracy isn’t always enough—especially for imbalanced datasets.
- Precision: % of true positives among predicted positives.
- Recall: % of true positives among actual positives.
- F1 Score: Harmonic mean of precision and recall.
- Confusion Matrix: Great for visualizing performance across all classes.
Example:
“In a fraud detection model, I’d prioritize recall to catch as many fraudulent cases as possible, even if it means a few false positives.”
4. Overfitting vs Underfitting, Bias-Variance Tradeoff
In this section you can prepare for both situations and academic subjects questions.
“What is overfitting and how can you prevent it?”
Overfitting = model memorizes training data, performs poorly on unseen data.
Underfitting = model is too simple, fails to capture patterns.
Solutions for Overfitting:
- Cross-validation
- Regularization (L1/L2)
- Dropout (for neural nets)
- Pruning (for trees)
Bias-Variance Tradeoff:
- High Bias = underfitting
- High Variance = overfitting
- The goal is to strike the right balance (low total error).
5. Feature Engineering & Data Preprocessing
This is a chance for you to show your practical abilities. Anticipate:
“How do you handle missing values or outliers?”
Good answers include:
- Imputation techniques: mean, median, mode, KNN imputation
- Outlier detection: z-scores, IQR, visualizations (box plots)
- Encoding: one-hot, label encoding for categorical variables
- Scaling: MinMaxScaler, StandardScaler, especially for algorithms sensitive to feature magnitude (like SVM or KNN)
Bonus: Talk about feature selection techniques like:
- Recursive Feature Elimination (RFE)
- LASSO regularization
- Mutual Information
