1. What is the Difference Between a Formula and a Function in Excel?

Aspect	Formula	Function
Definition	A user-defined expression that performs calculations	A pre-defined formula in Excel that performs a specific task
Example	=A1+B1	=SUM(A1:B1)
Created By	User	Built into Excel

Explanation:
A formula can be customized for calculations like =A1+B1–C1, while a function is a predefined command like SUM, AVERAGE, or VLOOKUP.
Recruiters often ask this to check your understanding of Excel’s computational logic.

---

2. Explain VLOOKUP Function and Its Syntax

The VLOOKUP function is one of the most asked Excel interview topics.

Syntax:
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

Example:
To find the department of employee ID 102:
=VLOOKUP(102, A2:D10, 3, FALSE)

Parameter	Meaning
lookup_value	The value to search for
table_array	The range of cells containing data
col_index_num	Column number of the result
range_lookup	TRUE for approximate match, FALSE for exact match

Tip: Many recruiters also test your ability to use VLOOKUP with IFERROR to handle missing data:
=IFERROR(VLOOKUP(A2, B2:D10, 3, FALSE), "Not Found")

---

3. What is the Difference Between COUNT, COUNTA, COUNTBLANK, and COUNTIF?

Function	Purpose	Example
COUNT	Counts numeric cells	=COUNT(A1:A10)
COUNTA	Counts non-empty cells	=COUNTA(A1:A10)
COUNTBLANK	Counts empty cells	=COUNTBLANK(A1:A10)
COUNTIF	Counts cells matching a condition	=COUNTIF(A1:A10, “>50”)

Interview Tip:
Employers use this to test your understanding of data cleaning and validation.

4. What is a Pivot Table and Why is It Used?

A Pivot Table summarizes large datasets dynamically.
It allows grouping, filtering, and analyzing data quickly without using formulas.

Use Case	Example
Sales Analysis	Sum of sales by region
Attendance Report	Count of employees by department
Finance Data	Total expenses by category

Recruiter’s Expectation:
You should be able to explain how to:

• Drag fields into Rows, Columns, Values, and Filters areas.
• Apply filters or slicers.
• Refresh Pivot Table data.

According to LinkedIn’s 2025 Job Skills Report, Pivot Table mastery ranks among the top 3 Excel skills employers look for.

5. Explain the Difference Between Absolute, Relative, and Mixed Cell References

Type	Symbol Example	Description
Relative	A1	Changes when copied
Absolute	$A$1	Remains constant
Mixed	$A1 or A$1	Partially locked

Example:
When you copy =A1*B1 to the next cell, both references change.
But with =$A$1*B1, A1 remains fixed.
This is often tested to check your referencing knowledge in formula building.

---

6. What is Conditional Formatting and How is It Used?

Conditional Formatting allows automatic formatting of cells based on set criteria.
For example:

• Highlight values above average.
• Change color for duplicate entries.
• Apply data bars, color scales, or icon sets.

Use Case Example:
Highlight all sales above ₹50,000:

• Select range → Conditional Formatting → “Greater Than” → Enter 50000.

Why It’s Important:
It helps visualize trends instantly — a critical reporting skill.

7. How Does the IF Function Work in Excel?

Syntax:
=IF(logical_test, value_if_true, value_if_false)

Example:
=IF(B2>=60, "Pass", "Fail")

Scenario	Result
B2 = 75	Pass
B2 = 55	Fail

Nested IF Example:
=IF(B2>80,"A",IF(B2>60,"B","C"))
Common in HR, Finance, and Student Report applications.

8. Explain the Use of INDEX and MATCH Functions

INDEX: Returns value from a specific row and column.
MATCH: Finds the position of a value in a range.

Combination Example:
=INDEX(C2:C10, MATCH("John", A2:A10, 0))

This combination is more powerful than VLOOKUP, as it can look left and is faster with large data.

Recruiter’s Note:
Many advanced Excel-based roles prefer INDEX-MATCH expertise over VLOOKUP.

9. What Are Excel Charts and How Do You Use Them?

Excel Charts convert raw data into visual insights.
Common types include:

Chart Type	Use Case
Column/Bar	Compare categories
Line	Show trends over time
Pie	Show proportions
Combo Chart	Compare two data sets
Scatter Plot	Analyze correlation

Example:
To visualize monthly sales growth, use a Line Chart with “Month” on the X-axis and “Sales” on the Y-axis.
According to research, charts improve business report readability by 60%.

10. Explain Data Validation in Excel

Data Validation restricts what can be entered into a cell.
Example use cases:

• Allow only numbers between 1 and 100.
• Create a dropdown list for departments.

Steps:

1. Select cell → Data → Data Validation.
2. Choose “List” → Enter options (e.g., HR, Finance, IT).

It ensures data consistency and prevents errors during data entry.

11. What is the Use of the CONCATENATE (or CONCAT) Function?

It joins multiple text strings into one.

Example:
=CONCATENATE(A2, " ", B2) or =CONCAT(A2, " ", B2)

If A2 = “Himanshu” and B2 = “Dhar” → Result = “Himanshu Dhar”

Practical Use: Combine first and last names, or merge city and pin code.
