How To Pass A SQL Interview For A Data Scientist Position - Issue 140
A case study challenge breakdown for a data scientist position solved in SQL
Welcome to the Data Analysis Journal, a weekly newsletter about product analytics and data science.
With continuing layoffs this year, I know many analysts are interviewing now. Today I want to share an example of a technical coding interview question for a data science position at Meta - and offer one of the solutions for solving it. I’ll walk through the steps on how to best approach and break down the problem and solved it using SQL.
Data Science is a cross-functional role, and candidates are tested across product and business acumen, data analysis, statistics, and modeling. The technical interview consists of Python and SQL questions. I covered an example of a Python interview a few months ago (read How To Pass A Technical Assignment For Senior Data Scientist Position), but today will focus solely on a SQL challenge that is aimed to test not only candidates’ code level proficiency but also business knowledge. For this task, it is expected you are proficient in SQL and data analysis.
