Google has a reputation for asking difficult, brainteaser interview questions that challenge how you act under pressure.

Most of them require you to think quantitatively and broadly, and test the way you tackle problems on the spot.

Google probably switches up its questions over time, but career website Glassdoor provides a glimpse of the types of brain-stumping puzzles Google has asked in the past.

Not all of Google’s tricky questions are necessarily meant to be brainteasers–some of them sound simple but turn out to be difficult to answer in a concise way.

Will your interviewing manager ask these questions?  Probably not but TMC would like to help you get in the right frame of mind before your interview.
