A recent CNN article explains well why a growing number of companies and puzzles logic puzzles make use of a type called guesstimations "during job interviews:
- "Seemingly random questions like this have become common in Silicon Valley and other tech outposts, where companies are not as interested in the answer to a difficult question, how in a prospective study, because workers could groped for solve it. Today, businesses must be able to respond quickly to market changesDynamics, want more engineers with high IQ and a good university transcripts. We want people who can think on his feet. "
What are technology companies (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, working memory, decision making, even emotional self-control (nottry to solve one of these puzzles, while 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 help you discover (or Google) the right answer, but a) identify the logical approach to "guesstimate" an appropriate range, say + or - 30% of the actual response, and then 2) complete calculations(Ideally, mentally, but you can also take notes), 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: Kevin, Jose, Hugh.
7) What is the weighta 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 fire of 1700 totalStaff.
3) There are over 26,000 trees (approximately 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 TakeoffWeight: about 374 000 tons or 825,000 pounds - For context, the weight of an empty lobster £ 8,600.
More context of executive functions:
Read more, learn what they want, here's a few quotes 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 executive brain. The prefrontal cortex is youngof evolutionary concepts, and is the brain region critical situations, adapt, for future planning and to adjust our operations 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 in which I explain how I made my flight was to organizeRussia to the United States. Significantly, the pathways connecting the frontal lobes with 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.
