Some hiring managers like to ask tough questions to test a candidate's reasoning skills or ability to think quickly and effectively under pressure. Others aren't quite sure what to ask, and revert to trendy brainteaser questions.

Regardless of the reasoning, it is important to be prepared for whatever may be thrown your way.

If the idea of having to answer a riddle fills you with dread, don't worry. "Often the interviewer does not know the answer, and there may be more than one," career coach Alice J. Goffredo explains in a LinkedIn post. 

The answer is not what's important here. Rather, it's about how you worked through the problem. "It's how you handled yourself. It's how you explained your rationale and how you defended it," she writes.

If you're thrown a curveball, Goffredo offers a few tips for handling the situation:

1. Keep your cool. "Try not to get confused or flustered," she says. "Your reaction to the question and the way you act while attempting to solve it is important."

2. Use your resources. "Because you brought a portfolio with your résumé, your questions, paper, and a pen, feel free to use your pen and paper to help you solve the question," Goffredo recommends.

3. Take your time. "Don't rush — even if you are being timed — take a deep breath, understand what's being asked of you and begin to work your way through solving it," she says.

Now that you know how to handle tough questions with confidence and ease, keep scrolling to see if you can answer these seven brainteasers Goffredo shared in her post.
