Being one of the world's largest tech and e-commerce companies, it’s no wonder that Amazon has done a lot to integrate machine learning and artificial intelligence applications to optimize its operations and services. Machine learning engineers play a crucial role in Amazon’s data science team. They research, build, and design the AI responsible for machine learning. They also work to maintain and improve existing AI systems.
A typical salary of an Amazon machine learning engineer is $153,661 per year. Understandably, Amazon interviews are as competitive as the salary they offer. Amazon's robust machine learning interview process includes an initial screen, a technical interview, and an on-site interview.
We’ve curated some Amazon machine learning interview questions to help you gauge your preparation level for your Amazon ML interview. Read ahead to learn more!

In this article, we’ll cover:
We’ll begin with some sample Amazon machine learning interview questions and answers to get a basic idea of what to expect.
Dropping the rows or columns with the missing or corrupted dataset or replacing them entirely with a different value are two easy ways to handle such a situation. Methods like IsNull(), dropna(), and Fillna() help in accomplishing this task.
Sentiment Analysis, Email Spam Detection, Fraud Detection, and Healthcare Diagnosis are some applications of Supervised Machine Learning.
Ensemble learning involves meta-algorithms combining various ML techniques into a single predictive model. The aim of doing that is stacking, bagging, or boosting. That is, to improve predictions, decrease variance, or decrease bias.
Bagging is a way to merge the same type of predictions, whereas boosting refers to a method of merging different types of predictions. Bagging decreases variance, and boosting decreases bias, not vice versa.
K-means is an unsupervised learning algorithm, whereas KNN is a supervised learning algorithm. K-means is mainly used for clustering problems, and the KNN algorithm is primarily used for classification and regression problems.

Q1. Is machine learning used in Amazon?
Yes, widely. The aggregation and analysis of purchase data using ML lead Amazon to better forecast the product demand. The ML analysis of the consumer purchase patterns also helps Amazon spot fraudulent purchases.
Q2. What is the type of machine learning that Amazon uses for business?
Amazon ML uses logistic regression: logistic loss function + SGD for binary classification and multinomial logistic regression: multinomial logistic loss + SGD for multiclass classification.
Q3. How much does an Amazon machine learning engineer earn on average?
An Amazon Machine Learning Engineer in the United States typically earns about $153,661 per annum.
Q4. What are the three types of machine learning?
The three types of machine learning are unsupervised, supervised, and reinforcement learning.
Q5. Which algorithms are most widely used in machine learning?
Linear regression, Decision tree, Logistic regression, KNN algorithm, K-means, SVM algorithm, Naive Bayes algorithm, and Random forest algorithm are some of the most widely used algorithms in Machine Learning.
