Try your hand at solving these bizarre puzzles.
- Think you've been asked some tricky job interview questions? We've compiled a list of some of the toughest prompts people have faced.
- Examples include "How would you measure the weight of the earth?" (Facebook) and "Tell me a joke" (J.P. Morgan Chase).
- Note that Google, and possibly other companies, have stopped asking brainteaser-type questions in the last few years - so lucky for you, there's a chance you may not hear these at your next job interview.
Job interviews are stressful.
Even if the hiring manager is nice, and even if you feel you're a perfect fit for the role, no one would fault you for breaking out in a sweat and fumbling a few questions.
But some job interviews are more nerve-racking than others. Over on Glassdoor, people have shared the tremendously tricky (and frankly, often bizarre) questions they've been asked during interviews at Amazon, Microsoft, McKinsey & Company, and elsewhere.
Google has said it's banned brainteaser-y questions, with other companies following suit. So, you may not encounter these exact questions in your job interviews.
Still, it's worth trying your hand at these puzzles to see how well you'd fare in these job candidates' shoes.
