    It is a silly question - but, What's the role of mental math & brain teasers in interviews?

    brain teaser brainteaser mental math
    Most recent answer on Nov 16, 2020
    <p>Hello,</p> <p>I know that these are silly questions. But, I hope you can spare a minute to entertain this silliness.</p> <ul> <li>Why is it important to have a good mental math "power" when we have our calculators in our phones? </li> <li>How do brain teasers help in interviews?</li> <li>AND; are there any tips to approach mental math or brain teasers in a more efficient way?</li> </ul> <p>I would love to hear from the experienced people here.</p> <p>Generally speaking, I am a bit on the slow side. It takes me few seconds to solve a 2 digit by 2 digit problem. It would take me even longer to do the "more complex" ones. That is a problem for me.</p> <p>I am practicing more and more and hoping to gain back the skills that I have long lost.</p> <p>I appreciate your input and feedback.</p>
    Hi Anonymous, I agree with Vlad, brainteasers are not very common (referring to my experience, when I applied, I got 1 out of 20+ interviews). Still, answering to your question, why do they ask them? The main reason ... (read entire answer)

    Most recent answer on Oct 23, 2020
    <p>I was given the following case study question during an onsite interview in a consulting firm. I am not sure if my approach was on the right track and would like to get some feedback here if possible to potentially improve my thinking process in the future. </p> <p>Question: A retailer increases prices for both iphones and windows phones, but the average selling price/phone sold from these two products has a decline. What are your approaches to explain this scenario? </p> <p>Thank you. </p>
    Hi! This can only happen if the two phones have different price levels, and a shift towards the cheaper phone has happened after the price increase, and the price of the cheaper phone after the price increase is still ... (read entire answer)

    Are brain teasers actually used in consulting interviews?

    brainteaser Case Interview
    Most recent answer on Apr 30, 2020
    <p>Brainteasers such as <a href="https://www.preplounge.com/en/daily-brain-teasers.php" target="_blank" rel="noreferrer noopener">https://www.preplounge.com/en/daily-brain-teasers.php</a></p> <p>(I'm not talking about "creative" market sizing questions like "How many golfballs fit in an airplane?")</p>
    Hi! the use of Brainteasers differs across the tiers: Not used in MBB Sometimes used in Tier 2 firms (Berger, Wyman etc.) Frequently used in Tier 3 firms (AD Little etc.) Cheers, Sidi

    <p>I got this question during an interview for a non-consulting job before I learned at all about structuring and break-down analysis tecniques (so I was not prepared at all!). At the time I went down a "number of tube stations X number trains that pass in one day" path and ended up completely lost in a tangle of unnecessary calculations. </p> <p>I'm curious to know how others would tackle this prolem. </p>

    <p>Hi</p> <p>I'd like to know the approach into calculating market sizing/brain teaser question that <strong>has no correlation to population. </strong>I find it hard to find formulas for these types of questions, for instance: how many pigs are there in China?</p> <p>Thanks</p>

    <p><strong>Estimate the number of radio stations that have more than 1 million listeners who listen at least once per month. </strong></p> <p>This is a question I found and didn't quite know how to approach it. I would also love to know what you think, is it a market size or a brainteaser question?</p>
    It looks like a bit of both market sizing and brain teasing. Assuming you have no data to work on, the interviewer wants to see how you think through and structure the problem. For questions like this (and most case que ... (read entire answer)

    <p>Hi Leute, ich komme bei obigem Guesstimate nicht auf eine vernünftige Herleitung. Meine Überlegung so far:</p> <p>- Es gibt insgesamt ca. 12 Mio. Leute zwischen 18 und 30</p> <p>- diese können 3 Dinge tun: Arbeiten, in Ausbildung sein oder Arbeitslos sein</p> <p>Das Beste was ich jetzt aber machen könnte ist, dass ich sage ich teile nochmal genauer ein und sage z.B. zwischen 18 und 22 gibt es halt 25% Berufseinsteiger und bei 23-26 vielleicht 35% etc. Aber das ist halt total angreifbar. Hat jemand einen TIpp und kann mir helfen?</p> <p>Danke</p>

    How many people enter the German job market per year

    brainteaser Case Case Interview Guesstimate
    Recent activity on Apr 29, 2018
    <p>Hi guys,</p> <p>I really do not know how to approach this kind of guesstimate. I mean i would start saying there are 80 Mio. in total in Germany and about 12 Mio around 18-30 years old. After that I can only say ok from the 18 to 22 years old 25% enter the job market, 23 to 26 35% and so on but that is not really detailed and easy to attack. Can you help me out and give me an idea for an approach. I would be very grateful. Thanks</p>
    Maybe oversimplistic but my approach would be the following: I would start by assuming that every person who is born in Germany at a certain point in his/her life (18,23,30 years old...) will start working then that's ... (read entire answer)

    <p>I got the strategy to answer market sizing questions like "How many petrol stations are there in city xx"?". You take assumptions like the population, number of cars, number of cars a petrol station can serve, etc. But what about questions like "How many elephants are there in the world?" Despite saying "There are elephants in Africa, Asia and in Zoos", I would not know how to continue. </p>
