Basic Excel Charts Interview Questions
1. What are the different types of charts available in Excel?
Answer: Excel offers several chart types, including:
- Column chart
- Bar chart
- Line chart
- Pie chart
- Area chart
- Scatter plot
- Combo chart
In Excel charts interview questions, you should explain when to use each chart. For example, line charts are ideal for trends over time, while column charts compare categories.
2. How do you choose the right chart for your data?
Answer: The right chart depends on the data and the business question. For time-based trends, use line charts. For comparisons across categories, use column or bar charts. For relationships between variables, use scatter plots.
During Excel data visualisation questions, interviewers look for logical reasoning behind your chart selection.
3. What is a Combo Chart, and when would you use it?
Answer: A combo chart combines two chart types, such as a column and a line chart, in a single visualisation. It is useful when comparing two different metrics with different scales, such as revenue and profit margin.
This is common in Excel dashboard interview questions for roles involving financial or operational reporting.
4. What is an Excel dashboard?
Answer: An Excel dashboard is a visual summary of key metrics and data insights displayed in a single worksheet. It typically includes charts, KPIs, slicers, and tables to provide interactive analysis.
In Excel reporting interview discussions, mention that dashboards should be clean, user-friendly, and focused on key objectives.

In Excel reporting interview scenarios, mention that it enhances visual clarity without creating additional charts.
10. What is Power Query, and how does it help in reporting?
Answer: Power Query is a data transformation tool used to clean, reshape, and combine datasets before analysis. It automates repetitive data preparation tasks.
In Excel dashboard interview questions, highlight how Power Query improves efficiency and data consistency.
