Top 35 Questions to Expect in a Meta Data Science Interview in 2025

This guide covers Meta's data science interview process, key topics, and tips for success.

Landing a data science role at Meta requires thorough preparation, and interviews here are known for their comprehensive evaluation of technical expertise, business insights, and problem-solving abilities. The following guide will walk you through 35 key questions to expect in a Meta data science interview, along with a detailed breakdown of the interview process.
‍

Interview Process at Meta


Here’s a brief overview of the typical Meta Data Science Interview Process:


1. Phone Interview


The first step is usually a phone interview. This is meant to check if you're a good fit for the role and to test some of your technical skills. You can expect to answer questions about how you’ve worked with data before, especially focusing on tools like SQL (used for working with data) and basic data analysis. They may ask you to solve a problem using SQL or to explain a project where you used data to find important information.


2. On-Site or Virtual Interviews


If you pass the phone interview, you’ll move on to several more interviews, which could happen in person or online. These interviews cover different areas:
‍

  • Coding: You’ll likely have to write some code, often related to data handling or problem-solving.
    ‍
  • Statistics: They will test your knowledge of statistics, which is important for understanding data trends and making predictions.
    ‍
  • Product Understanding: You’ll need to show that you understand how data can help improve Meta’s products.
    ‍
  • Machine Learning: They may ask about machine learning, which is about teaching computers to make decisions from data.
    ‍
  • Business Problem Solving: In some interviews, you’ll discuss real-world business problems and how data can be used to solve them.


3. Case Study


During the interview process, you might be given a case study. This is where you are given a set of data and a business problem to solve. You’ll need to look at the data, figure out what it’s telling you, and come up with ideas on how to fix or improve the business problem based on that data.


4. Final Interview


In the last round of interviews, they’ll ask more advanced technical questions. You may also be asked to dive deep into a particular business issue, using your data skills to come up with solutions. Additionally, they’ll want to see if you fit with Meta’s mission and values, making sure you would be a good match for the company culture.
