This Excel Interview Test has a total of 4 questions going from easy to hard. First we use conditional formatting to find the bottom 10 values. Second, we use a combination of an IF and an AND statement to accept or reject a project based on two criteria. Third, we use the goal seek tool on Excel under what if analysis to reach 5000 in profit. Finally, we use 2 different formulas to find the revenue in France for each month. For this we first use a SUMIFS with relative references. Second we use the XLOOKUP combined with the ampersand (&) so we can filter using multiple criteria.

your xlookup function only works because there are 1 unique France for each month. If you had multiple "France" for each month, only SUMIFS and using PIVOT table would work.

[@ianklimisch4139]

I would consider myself an advanced excel user, and had no idea I could add a 2nd criteria to Xlookup using & - I would have used index match! Great video

[@adrianstensrud]

Index match with multiple criteria is a bit more complicated though, but for sure, I would too. Never got into Xlookup as I never really needed it, and the naming criteria makes me sick after all of the years where people still uses VLOOKUP instead of Index Match.

[@adamhollander9487]

You can, but it's very computationally expensive for anything more than a couple dozen records. Your best bet is to combine the two criteria in a separate column first, or you're constantly going to be waiting for the sheet to calculate

[@Rohwi]

Personally I prefer another method where you lookup 1 in the result array of a product of the two conditions. for example =XLOOKUP(1,(A1:A4=D1)*(B1:B4=D2),C1:C4,"",0)

[@walterbierkens]

I would have used the SUMIFS and the SUMPRODUCT formulas.

[@supportive_comment]

During my interview with my current employer, I was given small tasks in Excel to 'prove' my qualifications. It's very similar, in fact, to this video. However, the thing my employer did to test me, which I think was harder to do, was decipher already written formulas. He gave me 3 different preexisting data tables with formulas already in them. He then told me to explain what the formuals were doing. The first 2 were easy enough, but the last one was absolutely atrocious. What got me the job was when I started deleting his formula and rewrote it in a cleanliner/more cohesive way.

The lack of ability by other employees to decipher formulas, pivots and other structures i developed, is o e of the reasons I'm irreplaceable. Thus is a lot i learned while back, to sometimes make the calculations more complex than they should be.

[@Lesardah]

Agreed. I'd hire someone like you over anyone who solved the actual formula. I always prefer someone who can look beyond their current task and ask a question like "What is this formula actually trying to do" rather than simply solving the given task. These types of folks usually move a little slower on the frontend, but save GOBS of time overall in trimming down old and obsolete business practices. Too many times I've heard the "because we've always done it this way" in response to why something exists. Wish there was a way to screen for people who think the way you do. I'm a working IT Manager (like, actually working with end-users as well as managing a small department over three locations). I don't have time or talent when it comes to hiring people - I've just been lucky to have an awesome HR department.

The third one I made a cell for "profit goal" and set it to $5000. If you do a little vit if algebra you'll realize you can get the number by dividing (fixed cost + goal profit)/(price per shirt - cost per unit). Use round up on that. Now you can change the goal profit, price per shirt, fixed cost, and cost per unit and it will adjust itself.

For question 3 I would add in "Required profit" to cell B9 and "$5000" to cell C9. Cell C11 is then a simple formula: =roundup(C9+C8)/(C6-C7) It's now dynamic and you can change the required profit to see how many sales it would need.

I would have used ab index match for the last one but I haven’t been taught the xlookup, it’s amazing what excel can do!

[@mattb8135]

Awesome tips! Here are a couple notes on Question 3 and 4: For Question 3, you can use Solver, rather than Goal Seek. Using Solver, you can create a parameter on the 'Units' sold to be an integer. That way you don't have to do the roundup formula at the end. For Question 4, you can use sumproduct for the second formula. =SUMPRODUCT(--($B$11:$B$22 = $B7), --($C$11:$C$22 = C$5), $F$11:$F$22). Then copy/paste across (Or Shift right and Ctrl R as you mention). Unfortunately, I would have to count points against someone for using any 'lookup' type of formula when summing numbers (even an Xlookup).

[@beezmemoire9376]

Is there a way you can show the exact formula so those not so familiar can better understand it? Thanks! 😊

[@counterleo]

True, in this dataset the couple CountryDate is unique so it is fine to find only the first match, but if there could be multiple rows for France and January arguably the question would want the sum of all matches not just the first one. The sum is conceptually superior. But then SUMIFS is the only elegant option, SUMPRODUCT is clever use of Boolean arithmetics but isn’t very readable.

[@mattb8135]

@@counterleo Once you get used to sumproduct, it's not too bad. In certain analytics departments, sumproduct is heavily used and preferred to sumifs as sumproduct is at least 1.5x more efficient at calculating on large data sets (or at least this used to be the case).

[@mattb8135]

@@beezmemoire9376 The Solver is a tool in excel (add-ins --> solver). I did show the sumproduct formula above. basically you put in a criteria like shown for B11:B22 and then equals to what you are trying to map to (in this case, b7). You can repeat this as many times as you want, just put a comma, then 2 dashes, then open parentheses, and do another check. when you get to the what you are actually trying to sum (like the 'sum range' in sumifs) you don't do the double dashes or parentheses (F11:F22 in my example above).

[@adrianstensrud]

@@mattb8135 Would also recommend cleaning up the formula a bit: =SUMPRODUCT( --($B$11:$B$22 = $B7), --($C$11:$C$22 = C$5), $F$11:$F$22 )

Learn something new every time you upload. I didn't know xlookup can do 2 lookups at once. I only knew index & match for Q4. So glad this channel exists.

[@counterleo]

Actually it doesn't do 2 lookups at once. It's a workaround. Under the hood, the & sign basically creates an invisible virtual column that consists of Country and Date just written back to back (concatenated). Same with the criterion. And then you match that virtual criterion to your virtual column. Whenever Excel finds a row where "CountryDate" equals "FranceJan-23" it will pick it 😂 Implicit requirement that the couple "CountryDate" is unique in the dataset, otherwise it will only pick the first one, whereas SUMIFS would sum all matching entries.

In his example there was one and only one record for each Country and Month, which is fine. But say you have multiple records for the same date and country, xlookup will return only the first match to encounter. sumif will do it correctly. So using xlookup is not a good example really, since there is a silent assumption made on how the underlying data is structured.

[@Hokiebird428]

I got 3 out of 4, but question 4 actually wasn’t the question I missed. I am actually extremely familiar with using lookup or match with multiple criteria, and in fact I believe there is a third viable formula you could use. However I have never used the What-If Analysis feature before, let alone the Goal-Seek tool. Maybe the test administrator could guide me to it like in the video, because I understood how it worked almost instantly. But I don’t know if that would have counted for a point or not. EDIT - A WORD OF CAUTION AGAINST USING A CONCATENATED ARRAY THAT I JUST EXPERIENCED THIS MORNING: If you are looking for criteria that are represented by numbers (for example I was looking to find a match for 1&21) you may find a false match for 12&1! Both evaluate to 121, so the match with the smaller row number will be selected, which was giving me an incorrect result! I find it much safer to use conditional statements multiplied together when I’m working with multiple criteria.

[@ScorpiusZA.]

For me question 1 to 3 was fine. Knew it before he started. On Q4, the first one, Sumifs, I got, but I would use a formula different to the Xlookup. Interesting how all sorts of ways to get to the same result.

[@adamwolach]

You may know this but for those who don't, sumproduct with three arrays evaluated to 1/0 does this easily. =sumproduct(array1, array2, array 3). Array1 would be countryrange=country, if you wrap it in parenthesis with --() it becomes 1/0: --($B11:$B22=$B6). Similarly the date lookup is --($C11:$C22=C$5). lastly the revenue is just the revenue array. To make life even easier, name the arrays. Then your sumproduct will look like this: =sumproduct(--(country=$B6),--(month=C$5),revenue) In essence, this runs a bunch of AND statements on each row in the multiplied arrays, so it will return 1 * 1 * revenue if everything matches, and return 0 if any criteria don't match, then adds them all up.

You won't have and shouldn't. Define the dataset and build the formula once, done. Giving defined names to cells, your formula bar should just have... =ROUNDUP((FixedCosts+SaleTarget)/SaleProfit),0) And that way if you get hit by a bus on the way to work, the work experience kid can read exactly what you did and life goes on...not for you, the business. You can load that up wherever you want for any product you want. Targets and costs can change and it'll just keep showing the correct figure. Job done once in a minute, never do it again. Querying the data and it'll be showing the correct adjusted figure when the file opens. That's literally all that Excel feature is doing, but you don't have to fiddle around with it every time. Always understand these kind of Excel features. Never use them unless one-off and it's fine to make a quick mess because the workbook is going to get deleted in a minute after.

As an analyst, I agree with other comments about Q2 but I see if from a different perspective and I contend that Kenji may have gotten it wrong himself. Extrapolating the minimum requirements of $500k revenue and $25k profit will result in a 5% margin (25/500). From Kenji's answer, Projects B and C are rejected due to them being less than $500k revenue, however Project B has an incredible 78% margin (over 15 times better than the minimum) and Project C's margin is 15.5% which is over three times better than the Minimum requirement.

[@evanfriedland6770]

The profit question can also be done algebraically. If you know profit = (price - cost) x quantity - 15000, then you can solve for the quantity at profit 5000 as quantity = (5000 + 15000)/(price - cost) which gives the same answer as above :)

On the last one the xlookup will only return a correct result if there's only one entry for France in each month. If there is a second entry you'll want to stick with the sumifs. If i had an interview on this, I think I'd have better results explaining that than I would by actually running an xlookup.

Thanks for the tutorial. For some reason, I don't understand the cell locking part with the F4 key. I need to understand how it can be done

Great stuff! So much fun and interesting these ‘exams’! I have a question about Q4; why in both answers when you refere to C5 you don’t lock the row like C$5 but keep it all open and use C5? And in the second answer when you use the xlookup, is it also possible to use a second xloookup function in this formula instead? Great btw to see the formula you use with the &, didn’t know this was possible! Thanks and keep teaching, you’re a natural.

Because you don't need to. The formula moves across, not down. You certainly could do it, but if you're trying to demonstrate mastery, then knowing whether or not you actually need to lock rows is a good thing to mention in your interview.

​@@B3Bandbut for the reference in B6, he left the row unlocked, as if he was preparing to copy the formula down as well as across. Say, if he wanted to add more country rows to a comparison. Just full locking B6 would have spared two hits of the F4 key.

I used to set an interview test when looking for trainers in an IT centre. It was to recreate an IDENTICAL table in EACH of the Office suite, including identical formatting. This was 25 years ago without instant tools. Of many candidates I found ONE. The only one who had been formally trained, not self- taught. To get the best out of software, and not make catastrophic mistakes, is to get a formal training.

this might be true 25 years ago but nowadays self training is more than adequate haha

[@Kerbeygrip]

@@ttsait my recent experience of self taught (in schools) is that I still receive documents which have been created “visually” , which when moved or imported “jump about” and need a global formatting to be of any use! The basics are missing! I am sure your courses are great. We just need more people to train!!!!

[@kamalsharma-nf5yv]

Interesting questions. I was confused about what the second method could be for the last question. Good to know XLOOKUP can be used like this. Thanks!

I have very limited knowledge of excel and I don’t use it for my job. I have no idea what I’m doing here but I still watched the whole thing 😂
