Premium questions with real-world problems
The General Data Science and SQL test assesses a candidate’s ability to analyze data, extract information, suggest conclusions, and support decision-making. It also tests a candidate’s knowledge of SQL queries and relational database concepts.
It's the ideal test for pre-employment screening. Data scientists and data analysts need to be able to extract knowledge and insights from data. Often, they also need a solid understanding of SQL to interface and access an SQL database efficiently.
This test requires candidates to demonstrate their ability to apply probability and statistics when solving data science problems and write SQL queries that extract and combine data.

Pass/fail grouping
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
Full customization
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Cheating protection
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
