The hiring agency, EQ Plus, is a leading South African IT recruitment and resource out-sourcing firm. They specialize in placing high-level technical talent into top-tier corporate environments. This specific role is for a client based in Menlyn, Pretoria, operating on a hybrid model, offering the perfect balance between office collaboration and home-office flexibility.
Role Overview & Technical Requirements
This role is for a “Full-Stack” BI Developer who understands both the visualization of data and the heavy lifting (ETL) behind the scenes.
- Dashboards & Reporting: Designing high-impact, interactive reports using Power BI.
- Big Data Processing: Using Azure Databricks to handle large-scale data engineering and analytical tasks.
- ETL Frameworks: Building and maintaining “Extract, Transform, Load” processes to move data from source to warehouse.
- Data Migration: Moving datasets across environments while maintaining data integrity.
- Connectivity: Expert use of various connectors to pull data from diverse sources into a centralized BI ecosystem.
Career Advice: The “Contractor” Mindset
- The Hourly Rate Advantage: At R450/h, the client expects immediate productivity. Your CV should highlight projects where you “hit the ground running.”
- Focus on the “Azure” Stack: Since they mentioned Databricks, they likely use the full Azure suite. Mention experience with Azure Data Factory (ADF) or SQL Server if you have it.
- Hybrid Logistics: Ensure you mention that you are within commuting distance of Menlyn. Being available for the in-office days is a non-negotiable for hybrid roles.
- Portfolio of Work: BI is visual. If you can, describe a specific dashboard you built that solved a business problem (e.g., “Reduced reporting time by 40% through automated Power BI refreshes”).
Possible Interview Questions
“Walk us through your experience using Azure Databricks for data transformation.” Answer: Discuss how you use Spark or SQL within Databricks to clean and aggregate data before it reaches the reporting layer. Mention “Medallion Architecture” (Bronze, Silver, Gold layers) if you are familiar with it.
“How do you handle performance issues in a Power BI report with millions of rows of data?” Answer: Talk about optimizing DAX queries, using “DirectQuery” vs. “Import” mode correctly, and performing as much data transformation as possible “upstream” in the ETL phase rather than in the report itself.
“Tell us about a complex ETL framework you’ve assisted with.” Answer: Describe the source of the data, the challenges (like bad data quality or slow connectors), and how you ensured the final dataset was accurate and delivered on time.
“Why is documentation important when migrating datasets?” Answer: Documentation ensures data lineage (knowing where data came from) and helps future developers understand the logic used during the migration, preventing “black box” systems.
