When you go for a job interview, it's always a mystery what questions they'll ask. Some hiring managers have a set of questions, all typed up, that they ask each candidate. Others like a more free-form interview, where the conversation just flows. And some places want you to present samples of your work, or even solve one of their current problems.

And then, there are hiring managers like these, who ask totally bizarre questions. Glassdoor has gone through their massive database of questions that people have been asked during a job interview in the United States and come up with the ten strangest ones over the past year. I don't endorse asking any of these questions unless you can justify why it's valuable to the job. But, go ahead and be glad no one asked you these questions.

1. "When a hot dog expands, in which direction does it split and why?" -SpaceX Propulsion Structural Analyst job candidate (New York, NY).

2. "Would you rather fight 1 horse-sized duck, or 100 duck-sized horses?" -Whole Foods Market Meat Cutter job candidate (Lexington-Fayette, KY).

3. "If you're the CEO, what are the first three things you check about the business when you wake up?" - Dropbox Rotation Program job candidate (San Francisco, CA).

4. "What would the name of your debut album be?"--Urban Outfitters Sales Associate job candidate (New York, NY).

5. "How would you sell hot coco in Florida?"--J.W. Business Acquisitions Human Resources Recruiter job candidate (Atlanta, GA).

6. "If I gave you $40,000 to start a business, what would you start?"--Hubspot Account Manager job candidate (San Francisco, CA).

7. "What would you do if you found a penguin in the freezer?"--Trader Joe's job candidate (Orange, CA).

8. "If you were a brand, what would be your motto?"--Boston Consulting Group Consultant job candidate (Washington, D.C.).

9. "How many basketballs would fit in this room?"--Delta Airlines Revenue Management Co-op job candidate (Cincinnati, OH).

10. "If you had $2,000, how would you double it in 24 hours?"--Uniqlo Management Trainee job candidate (Los Angeles, CA).

Now, keep in mind that these questions were reported by the interviewees, not the interviewers, so it might not be a perfect representation of questions asked, but it does demonstrate that there's a whole lot of strange going on out there in the interview world.

For the record, I'm betting, regardless of what a job candidate would say, the accurate answer for what someone would do upon finding a penguin in the freezer at Trader Joe's is whip out their phone, take a picture and post it to Instagram. That's probably not the answer the manager was looking for, though.

Weird interview questions aren't limited to the United States, though. Glassdoor also collected some from other countries. Here's a sample:

What was the last thing you Googled? Tim Hortons

If you were a utensil, which one would you be and why? Jack Astor's

If you were a fruit, what kind would you be and why? Topdeck Travel

How do you get an elephant in a fridge? Gemalto
