Preparation for the Initial Screening Round
In the initial screening round, you’ll be assessed on your past work experiences, knowledge of data handling, and coding abilities. Practice SQL and Python, and brush up on your data visualization skills. Revise basic statistical concepts and machine learning algorithms.
A casual chat with the hiring manager offers an opportunity to understand team dynamics, projects, and work culture. You can also express your interest and motivation for the role.
Deep Dive into the Onsite Interview
Onsite interviews are an intense process where your technical skills, problem-solving abilities, and cultural fittingness are scrutinized. Prepare to delve deep into your work experiences, coding abilities, and data modeling skills.
Round 1: Coding Interview
The coding round tests your capability to write and optimize code. Codility is often used for this. Brush up on SQL and Python, especially data manipulation packages like Pandas and Numpy.
Round 2: Machine Learning Principles
Here your understanding and application of machine learning principles are tested. Be ready to answer questions about bias-variance tradeoff, overfitting, regularization, different types of algorithms, and more.
Round 3: Designing a Data-Driven Solution
In this round, you’ll be given a business problem and you must propose a data-driven solution. This demonstrates your ability to apply machine learning concepts and derive value from data.
Round 4: Behavioral Round
Here you’ll be evaluated against Amazon’s Leadership Principles. Prepare stories from your past experiences that exemplify these principles.
Final Round: Statistical Inference and A/B Testing
Expect questions on probability, statistical inference, and A/B testing. Understanding the fundamentals of these areas is a prerequisite for a data scientist role at Amazon.
By the end of this rounds, interviewers will evaluate your ability to make an impact on the company’s future. Be ready to showcase data-driven solutions to real-world challenges, and speak confidently about your past experiences.
