The puzzle interview was popularized by Microsoft in the 1990s and is now used in other organizations. The most common types of questions either ask the applicant to solve puzzles or brain teasers (e.g., "Why are manhole covers round?") or to solve unusual problems (e.g., "How would you weigh an airplane without a scale?").

The Monty Hall problem is a brain teaser, in the form of a probability puzzle, based nominally on the American television game show Let's Make a Deal and named after its original host, Monty Hall. The problem was originally posed (and solved) in a letter by Steve Selvin to the American Statistician in 1975.
Each prisoner has to find their own number in one of 100 drawers, but may open only 50 of the drawers. The 100 prisoners problem is a mathematical problem in probability theory and combinatorics. In this problem, 100 numbered prisoners must find their own numbers in one of 100 drawers in order to survive.
Many candidates prepare to speak about their past experience and how it fits into the role, but many forget about the questions that ask them to describe how they are in the workplace, better ...
A trick question is a question that confuses the person asked. This can be either because it is difficult to answer or because an obvious answer is not a correct one. [ 1 ] They include puzzles , riddles and brain teasers .
The misdirection in this riddle is in the second half of the description, where unrelated amounts are added together and the person to whom the riddle is posed assumes those amounts should add up to 30, and is then surprised when they do not — there is, in fact, no reason why the (10 − 1) × 3 + 2 = 29 sum should add up to 30.
A coding interview is intended to seek out creative thinkers and those who can adapt their solutions to rapidly changing and dynamic scenarios. [citation needed] Typical questions that a candidate might be asked to answer during the second-round interview include: [7] Design a GPS navigation unit for a hiker.
One example in a game where combinatorial complexity leads to a solvability limit is in solving chess (a game with 64 squares and 32 pieces). Chess is not a solved game . In 2005 all chess game endings with six pieces or fewer were solved, showing the result of each position if played perfectly.
