Data Warehousing and ETL Tests for Hiring Engineers

This quiz assesses a candidate's knowledge of data warehousing and ETL ("extract, transform, load") tasks. It asks questions about data parsing and initial storage, scheduling and orchestration, processing approaches (e.g. batch vs streaming), auditability, data marts, and data modeling concepts like star schemas and slowly changing dimensions. It does not assume the use of any specific frameworks.

The Data Warehousing assessment tests understanding of handling big data, like ingestion, orchestration, processing, and cleaning.

• Understanding of data warehouse design, database design, schemas, tables, and constraints.
• Ability to compare the use-cases of different data warehouse architectures.
• Understanding of scheduling, automating, and monitoring ETL pipelines, and compare the use-cases of different data pipeline designs.

Assessments Engineers Actually Want to Take
Engineers don't want to take your outdated coding tests (you know they don't provide true signal anyway). Screen assessments have an 80-90% completion rate, so you don't have to worry about drop off.
Never miss the talented engineers in your pipeline again

Triplebyte tests are adaptive and use a nominal model for scoring. This allows for “partial credit” on multiple choice questions, to help identify unconventional thinkers vs. random guessers.

Screens that Scale with You
— and Your Candidates

Triplebyte Screen scales with you. Add as many team members as you want without the red tape of adding seats. Screen as many candidates as you want without having to ration assessments.

[After running an A/B test with both tools], I quickly found that the HackerRank signal was awful. People could score 20% or 80% and you still had no idea how good they actually are. But the Triplebyte Screen scores actually gave you insight.
If [the candidate] scores a 4 or 5 on Screen, we make an offer 50 to 60% of the time. "
