Sweet vid! Poker definitely helps out with mental math haha one trick that I use is using scientific notation when dividing two large numbers. For example if you were asked to divide 21 billion by 70 thousand you could just use 21 x 10^9 / 7 x 10^4. If you do 21/7 and then subtract 9-4 (from 10^9 and 10^4) your answer is 3 x 10^5(300k)!

[@neelandrohit6490]

Thanks Musa! And definitely, that's a great way to handle large numbers (and perfect examples that ties into Rohit's point on not writing out 0's)

[@shahannazim]

Great resource... its been very helpful in our journey of preparing for the consulting interviews

[@shaquillewalker9676]

I wish I knew these guidelines when I was applying to the Big 3 now! I'm at Bain currently and definitely think this advice is gold

[@neelandrohit6490]

Glad to see another Bainie here Shaq! Thanks for the support

[@bilalqazi7289]

The information you both put out, Neel and Rohit, is simple, yet so effective. This is the only resource I will use in the next two months (less is more). Thanks for giving back!

[@neelandrohit6490]

Great to hear Bilal! Let us know what else we can make to help (more casing videos on the way)

[@Sunny-tp2rt]

thank you for the video, it's very informative. Coordination of both of you is awesome Boss!

Fantastic to hear Sunny! Appreciate you letting us know

[@hibaelseed1313]

Very helpful, thank you so much ❤

[@DomAlexJapan]

Thank you so much for this video! I’m a humanities major about to start recruiting for consulting and my main worry has always been the maths, but seeing it broken down like this and all the shortcuts makes it seem a lot more manageable than I initially thought! Thanks a lot!

[@neelandrohit6490]

Glad it's helpful Dom! With practice, you'll be killing the math section!

[@bradsemmens8676]

Brilliant video guys, loved the math tips.

Thanks a ton Brad!

I am so impressed by you guys, not only because of the simplicity with which you both explain but mainly because of this whole work that you guys doing of helping out freely on this platform. Thanks alot again for sharing the resources and all the best to both of you for your respective future endeavours..

[@neelandrohit6490]

Of course, glad it's helpful!

[@lailarahman5575]

Would be better if you added some visual captions when you talk about the math tricks and processes. Since Neel talks pretty fast, having something to look at while hearing about the same thing, really helps visual learners.

[@ayushmittal2754]

How can you be so good... Watched every video at least 2 times. LOVE IT!!!!

[@neelandrohit6490]

That's amazing! Thanks Ayush

[@robertoovalle3404]

They work for one of the BIG FOUR! All of the big 4, and essentially the BIG 15 accounting and consulting firms have phenomenal training... but they also recruit the best, so these guys were probably geniuses already! LOL I think Boston Consulting Group[ (BCG) has the best training, followed by Ernst & Young.

[@raniazarandah9479]

Amazing work you guys keep it up!

[@neelandrohit6490]

We'll try out best! Thanks Rania And always welcome feedback on how we can improve the channel for you, so feel free to let us know!

[@mbhardwaj7714]

loved this video guys, as always :) scientific notation, in addition to writing say 10k. then also, writing explanations next to numbers if it's a numeric heavy case so you remember what values you had found for what later on! ps. please do a video with a math heavy case so you can show these tips in practice!

[@neelandrohit6490]

That's a great point! We'll add that to the list - I think a couple of people have asked for that now!

[@unlimitedsky8506]

Don't confuse calculations with math, this is mostly knowing how to calculate things and being trained on doing the calculations without a calculator. This is not the same as Math in general.

[@thetanuagrawal]

Wowww! Thanks for this,

[@neelandrohit6490]

Our pleasure!

[@colhornal1666]

As someone who isn't from a target school, I greatly appreciate your videos

Glad to hear it Col! Best of luck with your consulting application journey

[@adammiah4421]

Hey guys! Love your videos. Can you guys do a video on estimation?

[@simranb101]

Agreed! Would love to see a video on how to estimate populations for different countries, states, or regions. Honestly, would just love a general market sizing + estimation video (where you 2 go over some sample questions & your thought process in answering them)

[@TheIronhideChronicles]

Yeah, that would be helpful indeed

[@neelandrohit6490]

We can definitely do a video where we go over market sizings and how to make estimations for those! Good recommendation

[@olurolakemiodufowokan5001]

The video I needed!

[@neelandrohit6490]

Thank you!

[@alexanderszabo1629]

I actually do the same trick as Neel with the 25 (multiply by 100 and divide by 4), but would you personally recommend walking your interviewer through this thought process? Or else just saying "18 times 25 is.... 450"

[@neelandrohit6490]

Haha that's awesome to hear! I (Neel here) would recommend walking through interviewer through the math, but framing it more as you showing them the way you're doing the math rather than showing them as if they wouldn't know how to do it themselves. It's just about striking a balance between explaining and over-explaining (because your interviewer will likely be good at math too)

[@faithbrigade]

Where is the link of the video you guys mentioned?

[@shreekantacharya843]

Hey, I am planning to get into consulting. My background is in Loans and operations and I am a Bcom from Mumbai so please recommend a courses or specialization's that will help me land in one of the MBB?

[@neelandrohit6490]

Of course! We use excel all the time

[@MrCanadianplayer]

Hey guys, hope you're well. Awesome video!! It sounds super interesting :) I'm considering switching from my Accounting Major at McGill into one of the following.. I'm the first out of my family to go to college, didn't grow up in much wealth, I'd like to change that for myself. Which career, do you guys believe, provides me the best opportunity of a high earning potential (given I'd stay in MTL/Canada) 1. Civil engineer 2. Accountant/CPA 3. Finance (IB/Consulting/etc.) 4. Premed track What did you major in? Did you find your major helped you out in your current job? What do you recommend! Thanks guys! I know it's a little bit of an unconventional question, and hoping to hear your responses. Matan

[@neelandrohit6490]

Hey Matan, apologies for the late reply! Awesome story man, and best of luck changing your family's financial situation around. As for the career with the highest earning potential, my personal opinion (Neel here) is that finance will provide that. Specifically if you go the investment banking (or maybe even consulting) route into private equity. That's a sure-fire way, although quite stressful and demanding and selective, to get a ~$250K yearly salary just 3 - 4 years out of uni Have you made any headway on this decision since making your comment?

[@reelkrish]

Which system is used mostly the Indian system of Lakhs and Crores or Millions and Billions in Big3

[@PS-ls3xy]

Thanks, guys. the video linked for estimating the math fast is a scam - the guys does not explain the adjustent to the numbers rounded at all

[@neelandrohit6490]

Glad to hear you found our video useful. And sorry to hear the linked video didn't provide the value you were looking for. Were there any other videos that you thought explained it well?

[@amritsinghania2722]

U both from India?

[@neelandrohit6490]

Rohit has lived in India for several years in his life, and my parents are both from India (but I was born in the US).

[@ChatGPTofficialbot]

In life , when you are good at math , you'll soon be a giver !

[@franciscodagnino9280]

run away from consulting as fast as you can, now, go! Find something you're good at and sell that skill
