A good interview question can give you insight into a potential hire's critical thinking process, communication skills, and ability to think and execute on their feet. 

But with the the amount of prep they do these days, there's a good chance that your candidate has probably already heard just about every question you're about to ask them during their job interview.  

Glassdoor.com recently compiled a list of the top 25 oddball questions that big businesses, including Amazon and Trader Joes, ask during their hiring interviews. 

Here are 10 that will put your interviewee on their toes and hopefully give you a chance to see if they can think outside the box.
