The so-called "Fermi questions" are typical brain teasers in a job interview. Did you know the solution?
For
the interview
, you should not only be well prepared.
You should also be prepared for the fact that you will (possibly surprisingly) be given one or the other
task
that should show whether you can
think
along and keep calm - even if things get a little more complicated.
The
experts from "Karrierbibel.de" include the so-called "
Fermi questions
",
for example,
among the
typical
brain teasers in job interviews
.
To
put
it
simply, it means “
impossible estimation questions
” such as “
How difficult is Manhattan?
","
How many gardens are there in Germany?
"Or"
How many sheets of paper are copied in Germany in a day
".

The experts describe the challenge as follows: There cannot be a correct answer to this - simply because in many cases nobody knows such a thing.
Rather,
such questions are
about the
logical derivation
, it says on Karrierbibel.de - and the "
courage to think aloud
".
And the career advisors have another tip in case you are
asked
such a
tricky question
during the conversation
: The trick is
to break
the
task down into small subtasks
and thus find the solution.
Because: “What those present want to see is how systematically and analytically you approach a seemingly unsolvable problem.
After all, you can use this ability in your job. "
Using a
specific example
, the career portal explains how you can derive such a solution.
The question is
,
“How many piano tuners are there in Chicago?
"A possible
solution would
work like this ...
The
assumptions
are:
“About three million people live in Chicago.
About two people in one household.
There could be a piano in every twentieth household that is regularly tuned.
Pianos are tuned about once a year.
It takes about two hours to tune a piano, including travel time.
A piano tuner works an 8-hour day, a 5-day week and works 40 weeks a year. "
The
calculation
could therefore look like this: (3,000,000 inhabitants) / ((2 people per household) × (1 piano / 20 households) × (1 voices per piano and year)) = 75,000 times a year in Chicago you need a piano be tuned.
A piano tuner can do the following work:
(40 weeks per year) × (5 days per week) × (8 hours per day) / (2 hours per piano) = a piano tuner can tune 800 pianos per year.
The solution is
that there should be around 100 piano tuners in Chicago.

If
applicants should
actually get into such a situation in which they
come across a
question
that
at first glance seems unsolvable
, it is important to keep a cool head, take a deep breath - and then work out a possible answer step by step.
It is important to let the other person participate in the thought process.
Then even if the
candidates are
a little nervous, nothing should go wrong.
And remember: nobody is perfect.
Every
HR manager
knows that applicants are in a particularly
stressful situation
and will take this into account.
