A recent CNN article explains well why a growing number of companies using interviews riddles and logic puzzles of a type called "guesstimations" of work:
- "Seemingly random questions like that are now common in Silicon Valley and other tech outposts, Where companies are not so interested in the answer to a difficult question, as they are in perspective, as workers could groped for a solution. From today's companies must be able to respond quicklyChanging market dynamics, they want more than engineers with high IQ and good college transcripts. We want people who can think on his feet. "
What companies technology (Google, Microsoft, Amazon) and consulting (McKinsey, Boston Consulting Group, Accenture ...) looking for? Want to interview employees withbrain teasers good so called executive functions: problem solving, cognitive flexibility, planning, memory, decision making, even emotionalSelf-regulation (not groped to solve puzzles, while one of them angry or stressed).
Want to try a pair? Here are our first seven Guesstimations / Logic Puzzles for Brain Challenge:
Please try to guess the answers to these questions based on logical approach. The goal is not to discover (or Google) the right answer, but a) identify the logical approach to "guesstimate" an appropriate range, for example will help to + or - 30% of the actual response,and then 2) complete the calculations (ideally mentally, but you can also take notes), give an estimate.
Ready. Set. Go!
1) How many times heavier than a mouse an elephant?.
2) How many firefighters are in San Francisco?.
3) How many trees there are in New York's Central Park?.
4) How many shoes do you have in your life?.
5) How many balloons can fit in a school bus?.
6) In 1999, as these were baby names by popularity ranking: KevinJose, Hugh.
7) What is the weight of a large commercial airplane?.
The answer appears below. Again the key here is to try to plan the steps to be done to solve and find the mental calculations, a reasonable range. The brain is the challenge. The goal is not just the correct answer is found.
ANSWERS:
1) to 150,000. An average elephant weighs 4,000 kg on average, an average of 25 gram mouse.
2) About 350 firefighters in action on a given day,a pool of 1,700 firefighters overall composition of staff.
3) There are over 26,000 trees (about 175 species) in the park
4) Do not know (or should) know how many pairs you have had.
5) About 500,000, of which the bus is 50 balls high, 50 balls wide, 200 long balls.
6) Rank of boys' names in 1999, according to the Social Security Administration: 1 Jose (# 30), 2 Kevin (# 32), 3 Hugh (# 830).
7) For a Boeing 747 - Empty: around 400,000 pounds (lbs), or 181 000 tons - Maximum Takeoff Weight: approx 825 000 GBP or 374 000 tonnes - the context is the empty weight of a Hummer £ 8,600.
More context of executive functions:
Read more, learn what they want, here are some excerpts from my interview with neuropsychologist Dr. Elkhonon Goldberg
- Alvaro Fernandez: Please tell us more about what are the frontal lobes.
- Elkhonon Goldberg: We researchers typically call them the ExecutiveBrain>. The prefrontal cortex is young by evolutionary terms and is the brain region critical situations, adapt, for future planning and to adjust our actions to achieve the objectives of the new term. We could say that this part of the brain, just behind our forehead, acts as a conductor, directing and integrating the work of other parts of the brain.
- I offer a good example in the brain Executive book where I explainHow can I organize my escape from Russia to the United States. Significantly, the pathways connecting the frontal lobes and the rest of the brain that matures slowly, reaching full operational state aged between 18 and 30, or maybe even later. And how much hard-wired brain rather than in other parts of it are usually the first areas to decline.
