what's up everyone it's kenji here and today we'll聽 go over some of the most common excel interview聽聽
[5]
tests that i've encountered both recruiting for聽 finance roles as well as more business oriented聽聽
[10]
roles especially in big tech and here's some聽 general guidelines about them these tests are聽聽
[14]
often time constrained at around 30 minutes so聽 you don't really have time to be typing things聽聽
[19]
manually also they're very result oriented so they聽 won't really ask for things like the syntax of a聽聽
[24]
formula or which tab can you find a certain tool聽 in instead it's up to you to figure out what tools聽聽
[30]
work best to reach the desired output and these聽 excel tests can be split into two main categories聽聽
[35]
on the one hand you have formulas where you might聽 need to include some ifs index matches or lookups聽聽
[41]
while the other one has to do with data cleaning聽 where you might need to use some text functions聽聽
[45]
you might need some numbers formatting text聽 columns other things like that to clean up a聽聽
[49]
data set in this video we'll look at case studies聽 of both so let's get into it and you can download聽聽
[55]
the file i'll be working with for free in the聽 description so here's the document with the excel聽聽
[59]
test and it's got two different tabs one going聽 over formulas and the other one to do with the聽聽
[63]
data cleaning side so just general guidelines it聽 says to fill in these light blue areas over here聽聽
[68]
and the instructions are that we need to use two聽 different formulas to find the net income in new聽聽
[73]
york for the period between january and may and聽 it's quite common where they don't actually tell聽聽
[77]
you what formula to use instead it's up to you to聽 try to figure that out and there's generally more聽聽
[82]
than two right answers like they ask for here聽 so there should be plenty of room for you to聽聽
[86]
try different ones basically we want the formula聽 that's going to say that if it's currently january聽聽
[90]
and if it's in new york then we want to get the聽 net income for that and so we'll go equals some聽聽
[96]
ifs that's the first one we'll be using you can聽 see the instructions on what it does over here聽聽
[100]
press the top key the sum range is essentially聽 what we want as the output so it's the net income聽聽
[105]
for us that we're interested in we'll go ahead聽 and select it here press the ctrl shift down arrow聽聽
[110]
and then from there you have to press the f4聽 key you'll notice that that puts in a few dollar聽聽
[114]
signs in there and what that's saying is basically聽 that if we copy this across say all the way to may聽聽
[119]
this thing is going to stay fixated at net聽 income and it's not going to move across聽聽
[123]
so that's what we want press the comma key the聽 criteria range the first one let's say that's the聽聽
[128]
month and so we want the period to be within this聽 range over here press the f4 key again press the聽聽
[133]
comma key and we want that to be in the january聽 period you can't see right now but there it is聽聽
[138]
selected and for this one we're not going to press聽 the f4 key because we want that to move across聽聽
[142]
all the way to the different months聽 press the comma key the second criteria聽聽
[146]
has to do with the state so this is this聽 area over here ctrl shift down arrow聽聽
[151]
press the f4 key comma and then we want the聽 criteria itself to be the state of new york聽聽
[157]
we'll press the f4 because we don't really want聽 to have it move when we copy it across then close聽聽
[161]
the brackets and press enter from there we can聽 just go ahead and drag that and paste it across聽聽
[167]
that should be working for us to double check you聽 can get into this last one press the f2 key now聽聽
[172]
you can see that it's selecting this this over聽 here this month of may and same thing over here聽聽
[177]
and so on so that's looking good now we need聽 to find a different way to do this as well聽聽
[181]
the second formula that comes to mind is an index聽 match and it's actually a combination of two聽聽
[185]
different formulas one is an index and the other聽 one is a match and essentially it's gonna let us聽聽
[190]
select something horizontally and something聽 vertically which is essentially what we want聽聽
[194]
so it's actually quite similar to the sumifs so聽 we'll go equals index press the tab key and for聽聽
[201]
this this is the actual output that we want which聽 is the net income over here a bit like the sumifs聽聽
[205]
earlier press the f4 key to lock it comma now聽 we want the row number and that's where we will聽聽
[211]
would put the first match which is going to be聽 the horizontal one and the second one for the聽聽
[215]
vertical side so top press the match key press聽 the tab there the local value is the january聽聽
[221]
which is what we're looking for right now press聽 the comma key and the log up array is the whole聽聽
[225]
area over here which is a whole period press聽 the f4 key comma and the match type we want it聽聽
[230]
to be an exact match in this case so put the zero聽 close the brackets press the comma again and now聽聽
[236]
it's asking for the columns so for columns we want聽 new york so we'll go match again press the tab key聽聽
[241]
the local value is going to be new york comma the聽 lockup array is going to be the whole state area聽聽
[247]
press the f4 key to lock it and again in this one聽 i just forgot here but we need to lock this side聽聽
[252]
over here as well so i'll press the f4 key select聽 it all and then press the f4 and then lastly we聽聽
[258]
want it to be an exact match so we'll put a zero聽 close the brackets and then close the brackets聽聽
[262]
again for the index match press enter and now if聽 we've done this correctly it should give us the聽聽
[266]
same numbers as above that's a way for us to check聽 and that is the case so it's all looking good聽聽
[272]
moving on to the second question in this sheet聽 press the control down arrow to get to the bottom聽聽
[276]
here and here's the instructions it says to create聽 a drop down list by month that's the first step聽聽
[281]
and secondly to link the net income in new york聽 to the drop down list by month so what i think聽聽
[286]
this is saying is that hey if we select a certain聽 amount we want the net income to move dynamically聽聽
[290]
with it so if we have february here we want to see聽 the net income for february now firstly go ahead聽聽
[296]
let's go ahead and do the drop down list and for聽 that what comes to mind is a data validation so聽聽
[300]
for that we'll go under the data tab and then in聽 data validation which is this tick thing over here聽聽
[306]
click on it and we want to do a list essentially聽 that's going to show us all of the months and the聽聽
[310]
source here we'll go ahead and select it which is聽 basically all of these months that we have up here聽聽
[316]
and then we'll close that press the ok key and聽 now if we scroll down to the bottom here we should聽聽
[322]
have a drop down list and i think that's currently聽 the case where we can select a different month聽聽
[327]
so let's say we leave it at a march here and聽 now the second part to be honest it isn't all聽聽
[331]
that clear on this question and that's sometimes聽 the case where you need to interpret things a bit聽聽
[335]
yourself but i think what it's assuming is that聽 hey if we have a certain amount we want to find聽聽
[339]
the net income so it would be good to do some聽 sort of a lookup lookup function we'll go equals聽聽
[345]
type x lookup and here it's going to show you聽 the instructions of what it does so basically聽聽
[350]
what it's going to do is if we select the month of聽 march then it's going to look for that net income聽聽
[354]
in that period so we'll go ahead and press the聽 tab key to select it the local value like we said聽聽
[359]
is the current period comma the lookup array is聽 the range where it's going to be looking for it聽聽
[364]
and so we want to look for it up over here press a聽 comma key and then it's asking for a return array聽聽
[370]
so that's basically what is the return what is聽 it that you want so in our case we want the net聽聽
[374]
income right so we'll go ahead and select聽 that it doesn't really matter if we select聽聽
[378]
it from this first first row or the second row聽 as they're all the same numbers so we'll just聽聽
[382]
select the first one and then press enter and聽 from there in the period of march it says the聽聽
[387]
net income is 59 000. so let's go ahead and see聽 if that's currently the case and it is indeed聽聽
[392]
and now we can dynamically change聽 this so if we change that to january聽聽
[396]
then it moves all the way to 79 76 6 000 sorry聽 as that is the case here so it's looking good聽聽
[403]
moving on to the second section of the excel test聽 and over here we've got the data cleaning exercise聽聽
[408]
so the instructions here say that we need to聽 clean up this data set and create a table with聽聽
[412]
the first name the last name the phone number聽 and the state so here's the raw data and from聽聽
[418]
what you can see obviously it's looking quite聽 wrong it's not looking too great there's a lot聽聽
[421]
of uppercase layers where there probably shouldn't聽 be there's also some spacings here some things are聽聽
[426]
involved some things are italicized as well those聽 are things that we want to try to remove ideally聽聽
[432]
using formulas so i think the first formula that聽 we can use here is the trim which i'll just type聽聽
[437]
over here the idea is that this is going to聽 remove all of the spacings between the words聽聽
[441]
and it's only going to leave one space so equals聽 trim you can see the instructions of it over here聽聽
[447]
press the top key and just select it it's that聽 simple and then we just drag that down and there聽聽
[453]
you go now it's looking somewhat cleaner the聽 second one that we can use is known as the proper聽聽
[459]
and what this does ctrl b to bolden it and聽 what this does is it's gonna only put the upper聽聽
[464]
case on on the first letter of a word so for some聽 for example it would be just the s smith only the聽聽
[470]
s as well so we'll go equals proper press the聽 top key and we'll select this over here then聽聽
[477]
we can just drag that across now that's looking a聽 lot better as you can see over here it's looking聽聽
[482]
much more clean one thing that i think is聽 important to mention here is that you can聽聽
[486]
actually merge both the trim and the proper聽 function and put them all into one if you聽聽
[490]
ever wanted to so for example i can go here聽 under equals then i can do trim press the top聽聽
[496]
key and instead of selecting the text i'll just聽 put the proper inside it and then we select the聽聽
[501]
text which is this one over here and then we need聽 to close the brackets press yes and that's going聽聽
[506]
to show you the exact same thing over here press聽 the delete key to get that out also let's space聽聽
[511]
this out a bit more so for this one here press聽 the alt hoi that's going to open it up for us聽聽
[517]
and now it says over here up top that we need聽 to create a table with this so the first name聽聽
[521]
the last name phone number and state so basically聽 we need to try to categorize these we can actually聽聽
[526]
go one by one and just try to copy and paste them聽 which is obviously quite a bit tedious right you聽聽
[530]
could select this then copy it and paste it first聽 let's go and paste this as values so control c聽聽
[537]
and then over here you can press the alt h v聽 which is a shortcut for that so what i'm saying聽聽
[542]
is we could go say select sum and then ctrl c and聽 paste some say over here and then the next guy and聽聽
[548]
so on which is quite a bit tedious so press the聽 delete key we're not going to go through that聽聽
[553]
and instead what we can use is the text to columns聽 feature which is basically going to allow us to聽聽
[558]
categorize everything by a certain requirement聽 so for example if it has a space then it's gonna聽聽
[563]
break it down by that so we'll go ahead聽 and select this area ctrl shift down arrow聽聽
[568]
and then the shortcut here is the alt a e so it聽 just took us over here to the text of columns and聽聽
[575]
delimited is fine press next here and now the聽 delimiter here is basically what's what's the聽聽
[582]
breakdown so we want it to be split into spaces so聽 that's what you want to take over here so you can聽聽
[588]
see the data preview here where everywhere where聽 there's a space it's going to go into a new column聽聽
[593]
press next and then over in destination this聽 is basically where the output is going to be聽聽
[598]
i know destination sounds a bit fancy just聽 where it's going to be on the data set so聽聽
[603]
let's go ahead and select the range and聽 say we want to put it over by the h here聽聽
[608]
and then finish and now you can see that it's been聽 outputted as split column so once just the first聽聽
[614]
name last name so let's go ahead and categorize聽 them so first last and then here we want the phone聽聽
[621]
and then the state now that's looking a bit more聽 like it another thing that we should do here is聽聽
[626]
that the phone numbers you can see that typically聽 they have dashes between them so every three聽聽
[630]
numbers you might have a dash so let's try it and聽 do that ctrl shift down arrow and then we'll press聽聽
[635]
the ctrl 1 key that's going to help us reformat聽 the numbers from there we'll go under the custom聽聽
[640]
over here which is going to let us customize聽 it and what we want to put is this number sign聽聽
[645]
and we want to put it three times then after we聽 want to put the dash three more times and then聽聽
[651]
three more times there so the numbers are gonna聽 essentially look like an actual phone number press聽聽
[655]
the ok key then you can see here that you can聽 actually see them so press the alt hoi which is聽聽
[661]
going to reformat things so they look a bit more聽 spaced out now that's looking slightly more like聽聽
[666]
it that being said because this is all us numbers聽 we could actually just put a plus one and then put聽聽
[671]
brackets between the first three numbers so we'll聽 go ahead and select them again ctrl shift down聽聽
[676]
arrow ctrl one again and under custom at the very聽 beginning here we're just gonna put a plus one聽聽
[682]
and then we'll put a space and then we'll start聽 putting the um parenthesis at the start and the聽聽
[688]
end of the first three values press the ok key聽 and now that's actually looking a lot more like it聽聽
[693]
lastly for the states here we could actually聽 make them uppercase mainly because well states聽聽
[698]
are usually both letters in uppercase so we'll聽 go equals upper press the top key and that's聽聽
[704]
just gonna put everything in uppercase we'll聽 select it and then just drag that down over here聽聽
[710]
then we're gonna paste it as values so for that聽 ctrl c and then alt h v v and this way we can just聽聽
[717]
drag that across so control x and then ctrl v聽 and now that's looking a lot more like it let's聽聽
[723]
finally reformat this a bit so it looks a bit聽 fancier so ctrl b and we can also change the fill聽聽
[729]
color so alt h h and from there we'll select say聽 a dark blue like so and then alt h fc that's gonna聽聽
[736]
change the colors and we put the white over here聽 so we can see it a lot better uh one final thing聽聽
[741]
maybe for the state we can actually align that to聽 the center so we'll go alt h ac and there you go聽聽
[748]
now we clean this data set from looking like this聽 as it was before all the way to this over here聽聽
[753]
which i think looks a little more professional聽 hopefully that would be enough for you to pass the聽聽
[757]
excel interview and if you're liking this video聽 you can also check out our excel for business聽聽
[762]

[767]
looking to break into a business or a finance聽 role or those in it trying to level up their聽聽
[772]
excel game as well as going over the fundamentals聽 of formulas formatting and charts we also go over聽聽
[778]
case studies that replicate the type of work you聽 might be assigned in your day to day ranging from聽聽
[783]
financial modeling to cleaning a complex data set聽 and more so if you're interested in checking it聽聽
