Common ML Topics She Covers
Here are the top ML topics Emma Ding recommends mastering before an interview:
- Linear and Logistic Regression
Understand assumptions, cost functions, and where each is useful. - Decision Trees & Random Forests
Know how they handle categorical data and what overfitting looks like. - Gradient Boosting (e.g., XGBoost)
A favorite among interviewers—learn how it works and when to use it. - Evaluation Metrics
Precision, recall, F1-score, AUC—be ready to explain them with examples. - Bias vs Variance Tradeoff
You will be asked this. Emma says practice drawing this out. - Model Explainability
Tools like SHAP, LIME—know how to justify model behavior.
Emma Ding’s Sample Machine Learning Interview Question Breakdown
Let’s break down a question she shared:
Question: “You’re given a dataset of users and their click behavior. How would you predict click-through rate?”
Step-by-Step Breakdown:
- Understand the problem
CTR prediction = probability a user clicks = classification problem. - Start simple
Use logistic regression as a baseline. - Feature engineering
Create features like time spent, page depth, device type. - Model improvement
Try Random Forest, Gradient Boosting, test different splits. - Explain results
Show metrics (e.g., ROC-AUC) and explain trade-offs.

How to Prepare Like Emma Ding Recommends
Here’s a simple prep roadmap inspired by Emma’s method:
1. Start with Core Concepts
Use basic ML books like Hands-On ML with Scikit-Learn. Build intuition.
2. Code Every Day
Practice problems on platforms like LeetCode, Kaggle, and StrataScratch.
3. Mock Interviews
Join mock ML interviews on Interviewing.io or Peerlist.
4. Explain to a Friend
Emma often says, “If you can’t explain it simply, you don’t understand it.”
Real Example: How One Candidate Got Hired
An ML candidate named Raj used Emma Ding’s guide to land a job at Spotify. Here’s what he did:
- Practiced explaining confusion matrix scenarios.
- Prepared three ML projects he could walk through in detail.
- Repeated Emma’s CTR prediction case study with real datasets.
In the interview, he was asked almost the same question Emma had shared.
Raj says: “Following her structure helped me stay calm and communicate clearly.”

Tips to Sound Confident During Your Interview
Emma recommends these tips to boost your confidence:
Use phrases like:
- “Given the context, I’d begin with…”
- “My first instinct is to check…”
- “One tradeoff here is…”
Keep answers simple and structured. Don’t ramble.
Pause and think before answering. It’s okay.
