A recent CNN article explains why a growing number of companies and puzzles logic puzzles of a type called "guesstimations" used during the interviews:
- "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 it as today's businesses. must be able to react quickly to market changesDynamics, want 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? You want people with good brain teaser interview so-called executive functions: solving, cognitive flexibility problem, planning, memory, decision making, even emotional self-control (nottry to solve one of these puzzles, while 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, and then 2) complete calculations(Ideally, mentally, but you can also take notes), provide an estimate.

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: Generally the researchers call them the direction in the brain young. We have The prefrontal cortex isevolutionary terms, and is the brain area critical to adapt to the new plan for the future, and self-regulate our actions to achieve the 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 could organize my escapeRussia to the United States. Significantly, the ways to connect to the rest of the frontal lobe of the brain are a mature slowly, reaching full operational state between the ages of 18 and 30 years, or perhaps even later. And why are so hard-wired brain rather than the other parties, are usually the first areas to decline.
