Hello folks…
Time for a fun & useful survey. This time lets talk about Excel Interview Questions.
Many of you are silently becoming awesome in Excel, data analysis, charting, dashboard reporting, VBA, Power Pivot and business skills, thanks to all the time you spend on Chandoo.org. I am sure there will be a day in near future, when you have to face another interview and be selected for a challenging, fun & high paying role.
Likewise, there is also a significant portion of you who are too good in your job that you will become a senior manager, VP or CXO, or better still start your own business. When the tables have turned, you will be the one looking for smart, dedicated, talented and fun individuals to join your team and make you look even more awesome.
So my question for both prospective interviewees and wannabe Excel pros,
According to you, what are the best Excel interview questions?
I will go first.
My top 5 Excel interview questions
Assuming I am looking for an analyst who can take any data dumped at her and turn it in to insights, actionable statements or management summaries, I will ask her below questions for sure.
- How do you lookup particular items from a large data set? Discuss various approaches, why they work, where they fail using this example data set.
- Can you make this ugly, confusing model in to usable, simple & elegant one?
- Assuming you have sales data of various products in several regions over the last 36 months, what kind of charts you prepare to help us understand what is going on and where we should focus?
- Can you analyze the same sales data using pivot tables. Can you compare pivot analysis with formula approach and comment?
- How well do you know about our business? Can you create a high level model of how we make money in Excel? After I explain how we make money in words of course.
- Bonus question: Which resources you use to keep yourself ahead of others in this position. (websites, books, training programs etc.)

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
