Interviews are challenging. Job interviews that require any sort of tracking data or simple calculations are even trickier, as this would require a knack of MS-Excel.
Excel usage has been increasing in the industry; individuals manage their data in Excel to analyze the business trend.  And, it could be nerve-wracking for both the interviewer and the interviewee to face such questions. To prepare you for those frequently asked questions, here we present a library of 30 questions and answers picked from real interviews.
All the best!

Q1. What is Microsoft Excel?
Answer: Microsoft Excel is an electronic spreadsheet program, created by multiple highly skilled engineers from Microsoft. It enables users to organize, format, and calculate data with formulas using a spreadsheet system broken up by rows and column.
We also use this tool for storing, organizing and manipulating the data. In addition, it also offers programming that supports VBA, and we can use external database to make dynamic reports, analysis etc. Smart use of this program saves a lot of time and helps in creating our own applications too.
Q2. What is Ribbon in MS-Excel?
Answer: The ribbon in Excel consists of the tabs at the top. These tabs are split into groups which categorize related command buttons into sub tasks.
Each group has its respective command button and the dialog box launcher, which are present in the lower right corner in some of the groups.
This opens a dialog box containing a bunch of additional options we can choose from.

Q17. What is the use of Vlookup and how do we use it?
Answer:  Vlookup is used to find the data in the large spreadsheet by lookup value in another worksheet. To use the Vlookup function, we should have common values in both data. For example, we want to search the phone number of a person. So, in order to find out the phone number, we will need the concerned person’s name.
How do we use it?
We have 2 set of HR data in Excel. In the second data, we want to update joining date of every employee from the first data. To use the Vlookup function, data must have the common value.
image 18

Follow below steps:-
  • Enter the formula in cell G3
  • =VLOOKUP(F3,$A$3:$D$13,2,0)
  • Press enter and copy the same formula in the range F4:F13
image 19

Formula Explanation: =VLOOKUP(F3,$A$3:$D$13,2,0)
  • In this formula, F3 is the cell of common value or lookup value
  • Then we have selected the range $A$3:$D$13 to the 1st data
  • 2: we have defined to pick the value from the 2nd column
  • 0: we have defined for the exact match
Q18. How can we view the values in the right most column in Excel?
Answer:  We can view the value from the right most column through Index and Match function.
Example: We have 2 HR data in Excel. In the second data, we want to update joining date of every employee, from the first data. To use the Vlookup function, data must have the common value.
image 20

Follow below steps:-
  • Enter the formula in cell G3
  • =INDEX($A$3:$D$13,MATCH(F3,$B$3:$B$13,0),1)
  • Press Enter
  • Copy the formula in range G4:G13.
image 21
Formula Explanation: =INDEX($A$3:$D$13,MATCH(F3,$B$3:$B$13,0),1)
  • In this formula =INDEX($A$3:$D$13 this syntax is used to define the array from which we want to pick the value
  • MATCH(F3,$B$3:$B$13,0) this syntax will help to lookup the value
  • At last ‘1 define’ is to pick the value as result so 1 implies that we want to pick the value from the 1st column
Q19. How can we merge multiple cells text strings in a cell?
Answer: We can merge multiple cells text string by using the Concatenate function and “&” function.
Example: We have three names: First Name, Middle name, Last name in 3 columns. To merge the names and make it a full name, follow the steps below:
image 22
Concatenate Function
  • Enter the formula in cell D2
  • =CONCATENATE(A2,” “,B2,” “,C2)
image 23
“&” use in formula to merge the text:
  • Enter the formula in cell E2
  • =A2&” “&B2&” “&C2
