A recent CNN article explains why a guy called "a growing number of 'companies use puzzles and logic puzzles during job interviews guesstimations:
- "Seemingly random questions like these have become commonplace in Silicon Valley and other tech outposts, where companies are not as interested in the answer to a difficult question, as they are, as a prospective employee might try to solve as companies have today . be able to respond quicklyShift in market dynamics that more transcripts of engineers with high IQs and good college. You want people who can think on their feet. "
What are technology companies (Google, Microsoft, Amazon) and consulting firms (McKinsey, Boston Consulting Group, Accenture ...) looking for? We want people with good so-called executive functions interview Brain: flexibility and problem solving, cognitive, planning, memory, decision making, and emotionalSelf-regulation (do not try to solve puzzles, while one of them is angry or stressed).
Want to try some? Here we have our Top 7 Guesstimations / logic puzzles for Brain Challenge:
Please try to guess the answers to these questions on your logical approach. The goal is not to discover (or Google) the right answer, but 1) to identify the logical approach that will help "guesstimate" an appropriate range, say + or - 30% of the actual response, andthen 2) complete the calculations (ideally mentally, but you can also take notes), provide an estimate.

7) For a Boeing 747 - Empty: 400,000 pounds (lbs) or 181 000 metricTons - Maximum takeoff weight: 825,000 pounds or 374,000 tons - For context, the weight of the empty lobster £ 8,600.
The executive functions of another context:
To learn more about what they want to know, here are some 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 prefrontalCortex is young by evolutionary terms, and is the crucial area of the brain to adapt to new situations, plan for the future, and self-regulate our actions to achieve long-term objectives. We could say that this part of the brain, just behind the forehead, acts as a conductor, directing and integrating the work of other parts of the brain.
- I offer a good example in the book executive brain, where I explain how I can organize my escape from Russia wasUSA. Significantly, the ways in which the frontal lobes mature more slowly with the rest of the brain, reaching full operational state between the ages of 18 and 30 years, or perhaps even later. And because Wired is not as difficult as in other parts of the brain, they are to fall is usually the first areas.
