Independent Readiness Checks (Before Applying)
Can you independently perform these practical tasks without looking up syntax?
Validation: Use DENSE_RANK() OVER(PARTITION BY department ORDER BY salary DESC) to identify top-3 earners without syntax lookup.
Validation: Explain why Snowflake schemas with normalized sub-dimensions can slow down DAX performance compared to Star Schemas.
Validation: Write CALCULATE(SUM(Sales[Revenue]), SAMEPERIODLASTYEAR(DimDate[Date])) and verify correct total row behavior.
Validation: Record a Loom video explaining the core business takeaway from your dashboard in under 120 seconds.
Hiring Preparation & Scenario Interview Exercises
Realistic scenario questions, sample responses, and common mistakes.
Scenario Question 1: How do you handle a scenario where business leads report conflicting definitions for "Active Customer"?
Propose establishing a standardized data dictionary with explicit tiered definitions (e.g. "Engaged User" vs "Monetized Active User") aligned across stakeholders.
Choosing one team’s side without documenting the distinction, leading to inconsistent reports.
Scenario Question 2: Why did you choose a Star Schema over a Single Flat Table in your Power BI project?
Explain that Star Schemas optimize VertiPaq columnar compression, minimize redundant string memory, and ensure predictable DAX filter propagation.
Saying "because the tutorial told me to" or confusing relationships with SQL joins.
- Host interactive dashboards on NovyPro or Power BI Service with public view links.
- Maintain a clean GitHub profile with comprehensive READMEs containing business context, schema diagrams, and SQL scripts.
- Embed a 90-second video demo at the top of every repository.

Technical Interview Questions & Answers
Q1: What is the difference between RANK(), DENSE_RANK(), and ROW_NUMBER() in SQL?
ROW_NUMBER assigns a unique sequential integer to each row. RANK assigns identical numbers for tied values but skips subsequent numbers (e.g. 1, 2, 2, 4). DENSE_RANK does not skip ranks on ties (e.g. 1, 2, 2, 3).
Q2: Explain the CALCULATE function in Power BI DAX with an example.
CALCULATE evaluates an expression in a modified filter context. Example: CALCULATE(SUM(Sales[Amount]), Region[Country] = "India") calculates total sales specifically filtered for India.
Frequently Asked Questions
Do I need a Computer Science degree for Data Analytics?
