Google headquarters

The tech giant is notorious for its tough interview questions.

By now, you’ve probably seen one of the many articles that offer a look into a day in the life at a Google office — futuristic architecture boasting Google’s logo colors, rooms with bean bags and hammocks to take a mental break, and cafeterias with delicious-looking grub.

Basically, Google’s work environment is one that loads of people would dream of being a part of, but it’s easier said than done. The tech giant’s interview process certainly isn’t a walk in the park.

In fact, the company is notorious for asking interviewees brain teasers and questions that make you think out of the box in order to gauge how well you perform under pressure.
