Power BI building report

 Here’s the simplest way to remember, using the "3 C’s + VISUAL" method (easy to recall under pressure):

🧠 Memory Trigger: "3 C’s + VISUAL"

1. Connect → 2. Crunch → 3. Craft → VISUAL

1. CONNECT Data

• "Link to sources (Excel, SQL), clean in Power Query."

• Think: Plugging a USB cable.

2. CRUNCH with DAX

• "Calculate KPIs like sales growth and profit margins."

• Think: A calculator crunching numbers.

3. CRAFT Structure

• "Model relationships (e.g., Sales ↔ Products) and hierarchies (Year > Month)."

• Think: Building Lego blocks.

VISUAL (Dashboard Steps):

• Visuals (Cards, Charts, Maps)

• Interactivity (Slicers, Filters)

• Style (Colors, Fonts)

• Upload to Power BI Service

• Align Layout (Top → Bottom: KPIs → Trends → Details)

• Launch & Share

🗣️ Sample Answer (30 Seconds):

*"I use the 3 C’s:

1. Connect to data sources and clean it,

2. Crunch numbers with DAX for KPIs like YoY growth,

3. Craft relationships and hierarchies.

Then, I build VISUAL dashboards:

• Visuals like trend charts and sales maps,

• Interactive filters for regions/dates,

• Style it for clarity,

• Upload to the cloud,

• Arrange insights logically, and

• Launch for stakeholders."*

💡 Pro Tips to Nail the Answer:

1. Analogies Win:

   • "It’s like GPS: Connect (input destination), Crunch (calculate the route), Craft (turn-by-turn directions)."

2. Mention ONE Technical Detail:

   • "I always use a Date table for accurate time intelligence in DAX."

3. Star Schema:

   • Drop a term: "I structure data into fact/dim tables for efficiency."

4. Close with Impact:

   • *"This helps teams cut analysis time by 30% and focus on high-priority regions."*

🔑 Bonus: 10-Second Summary

"Connect data → Crunch DAX → Craft model → VISUAL dashboard. Focus on KPIs, interactivity, and clean design."

This sticks in your brain and covers everything interviewers want to hear. Adapt it with your experience! 😊

DASH-SALES Framework (Easy to Recall)

Data → Analyze → Structure → Hierarchy → Select Visuals → Arrange → Layer Interactivity → Enhance → Share

"I start by collecting and cleaning data in Power Query (D), 

then align on KPIs with stakeholders (A). 

Next, I structure the data model (S), 

add hierarchies and DAX measures (H), 

and select visuals like cards and line charts (S). 

I arrange them logically (A), 

add filters for interactivity (L), 

enhance with formatting (E), 

and finally share the dashboard (S). For sales, 

I focus on trends, 

regional performance, and YoY growth."
