Top 7 Brainteasers for Job Interviews and Brain Challenge

A recent CNN arti­cle explains well why a grow­ing num­ber of com­pa­nies use brain­teasers and log­ic puz­zles of a type called “guessti­ma­tions” dur­ing job inter­views:

- “Seem­ing­ly ran­dom ques­tions like these have become com­mon­place in Sil­i­con Val­ley and oth­er tech out­posts, where com­pa­nies aren’t as inter­est­ed in the cor­rect answer to a tough ques­tion as they are in how a prospec­tive employ­ee might try to solve it. Since busi­ness­es today have to be able to react quick­ly to shift­ing mar­ket dynam­ics, they want more than engi­neers with high IQs and good col­lege tran­scripts. They want peo­ple who can think on their feet.”

What are tech­nol­o­gy com­pa­nies (Google, Microsoft, Ama­zon) and con­sult­ing com­pa­nies (McK­in­sey, Boston Con­sult­ing Group, Accen­ture…) look­ing for? They want employ­ees withbrain teasers job interview good so-called Exec­u­tive Func­tions: prob­lem-solv­ing, cog­ni­tive flex­i­bil­i­ty, plan­ning, work­ing mem­o­ry, deci­sion-mak­ing, even emo­tion­al self-reg­u­la­tion (don’t try to solve one of these puz­zles while being angry, or stressed out).

Want to try a few? Below you have our Top 7 Guesstimations/ Log­ic Puz­zles for Brain Chal­lenge:

Please try to GUESS the answers to the ques­tions below based on your own log­i­cal approach. The goal is not to find out (or Google) the right answer, but to Read the rest of this entry »

Try to quick­ly ESTIMATE the answers to the ques­tions below, based on your own log­i­cal approach. The goal is not to find out (or Google) the right answer, but to, first, iden­tify a log­i­cal approach that can help “guessti­mate” an appro­pri­ate range–say + or – 30% of the actu­al answer– and then com­plete the cal­cu­la­tions (ide­ally men­tally, but you can also take notes) to pro­vide a good-enough esti­mate.

Ready. Set. Go!

Ques­tions:

1) How many times heav­ier than a mouse is an ele­phant?.

2) How many fire­fight­ers are there in San Fran­cis­co?.

3) How many trees are there in NYC’s Cen­tral Park?.

 

The Answer appear below. Again, the key here is to try, plan the steps towards the solu­tion, and do the men­tal cal­cu­la­tions to find a rea­son­able range. That’s the brain chal­lenge. The goal is not to find the pre­cise cor­rect answer.

Answers:

1) Around 150,000. An aver­age ele­phant weighs 4,000 kg; an aver­age mouse 25 grams.

2) Around 350 fire­fight­ers on duty on any giv­en day, out of a pool of 1700 fire­fight­ing over­all staff.

3) There are over 26,000 trees (of approx­i­mate­ly 175 species) in the Park.
