Interview Experience at Amazon ML Intern Position 2025

Interview Experience at Amazon ML Intern Position

I recently had the opportunity to interview for the Machine Learning (ML) Intern position at Amazon, and the experience was both insightful and challenging. The interview process consisted of several rounds, each focused on assessing different aspects of machine learning knowledge, problem-solving abilities, and coding skills.

The first round was a technical screening where I was asked basic questions to gauge my understanding of machine learning concepts and algorithms. Some of the questions included:

• Explain the difference between supervised and unsupervised learning.
• Describe the bias-variance tradeoff in machine learning and how it impacts model performance.
• Solve a coding problem involving data manipulation or basic algorithm implementation in Python or a similar language.

In the second round, I was presented with more in-depth questions related to machine learning algorithms and techniques. Some of the topics covered were:

• Explain the working principles of popular machine learning algorithms such as linear regression, logistic regression, decision trees, and k-nearest neighbors (KNN).
• Discuss the challenges and techniques for handling imbalanced datasets in classification tasks.
• Describe the steps involved in training a neural network model using backpropagation.

The third round focused on coding skills and problem-solving abilities related to machine learning. I was asked to:

• Implement a simple machine learning algorithm from scratch, such as linear regression or k-means clustering.
• Solve coding problems that require knowledge of data structures and algorithms, such as array manipulation or string processing.
• Write Python code to preprocess and analyze datasets using libraries like NumPy, Pandas, and scikit-learn.

In this round, I was asked to discuss my previous machine learning projects and experiences in detail. I presented projects I had worked on, explaining the problem statements, methodologies used, challenges faced, and the outcomes achieved. The interviewer asked probing questions to assess my understanding of the projects and the underlying machine learning principles.

The final round was a behavioral interview where I had the opportunity to showcase my soft skills, teamwork abilities, and problem-solving approach. The interviewer asked questions about my past experiences, motivations for joining Amazon, and how I handle challenges and setbacks in a team environment.
