This guide is for data science professionals looking to land a job at Meta, particularly those with 2-5 years of experience in data analysis and SQL. According to Levels.fyi, Meta data scientists typically hold a Bachelor's or Master's degree in Computer Science, Statistics, or Mathematics.
What Kind of SQL Questions Are Asked in Meta Data Scientist Interviews?
Meta data scientist interview SQL questions typically fall into three categories: data extraction, data transformation, and data analysis. Candidates are expected to write efficient and effective SQL queries to extract insights from large datasets. For example, in a recent interview, a candidate was asked to write a SQL query to extract the top 10% of users based on their engagement metrics.
How to Prepare for Meta Data Scientist Interview SQL Questions?
To prepare for Meta data scientist interview SQL questions, candidates should focus on practicing SQL queries on large datasets. This can be done by working on personal projects or participating in data science competitions. Additionally, candidates should review common SQL concepts, such as joins, subqueries, and aggregations. According to Glassdoor, candidates who practice with real-world datasets tend to perform better in the interview.
What Are the Most Common SQL Concepts Tested in Meta Data Scientist Interviews?
The most common SQL concepts tested in Meta data scientist interviews include data modeling, data warehousing, and data governance. Candidates should be familiar with data modeling concepts, such as entity-relationship diagrams and data normalization. They should also have experience with data warehousing tools, such as Amazon Redshift and Google BigQuery. In a recent interview, a candidate was asked to design a data warehouse schema for a large e-commerce dataset.
How to Answer Behavioral Questions in Meta Data Scientist Interviews?
In addition to SQL questions, Meta data scientist interviews also include behavioral questions. These questions assess a candidate's ability to work with stakeholders, communicate complex ideas, and prioritize tasks. To answer behavioral questions effectively, candidates should use the STAR method, which involves describing the situation, task, action, and result. For example, a candidate might describe a project where they worked with a cross-functional team to develop a data-driven product feature.
