So, you’ve polished your resume until it shines, memorized your elevator pitch, and practiced your handshake (yes, even if it’s virtual). You’re ready for your job interview… or so you think—until your interviewer throws interview brainteasers your way like, “Why are manhole covers round?”
Yep, that’s a real question. It’s actually one of the most popular brain teaser questions out there. And believe it or not, it’s now considered one of the easier ones. You can thank Microsoft for that.
Where Did These Weird Questions Even Come From?
Back in the day, Microsoft shook up the hiring world by tossing unexpected, questions like interview brainteasers. Think “How many golf balls fit in a 747?” or “Design an evacuation plan for San Francisco.” These questions weren’t about right or wrong—they were about how you think.
Soon enough, companies across industries jumped on the bandwagon. Consulting firms, investment banks like Goldman Sachs, even startups began slipping in quirky hypotheticals during interview brainteasers to see how candidates handle pressure and problem-solving on the fly.
It’s Not About the Right Answer
Here’s the thing—most of these questions aren’t meant to have a single correct answer. What hiring managers really want to know is how you think. They’re observing your reasoning process, your creativity, and your ability to stay calm while navigating a curveball.
One anonymous Microsoft contractor once said the goal isn’t to test who you think you should be, but to see who you actually are. Authenticity matters more than acting like a character out of “Suits.”
Examples of Common Interview Brainteasers
Not all interview puzzles are impossible. Some are just… unexpected. Take this one:
“What’s the angle between the hour and minute hands of a clock at 3:15?”
You might think “zero,” since the hands are close together—but nope. The correct answer is 7.5 degrees. And even if you don’t know that off the top of your head, showing how you approach the problem is what matters.
Then there are the estimation-style questions, like:
“How many gas stations are there in Canada?”
These types of questions are less about accuracy and more about logical thinking. Start big: What’s Canada’s population? How many cars might exist per household? How often do people fuel up? Walk through your reasoning step by step, and make it easy to follow. That’s gold during an interview.
Here’s another:
“What’s the size of the diaper market in China?”
You don’t need the exact figure. Just start with China’s population (around 1.4 billion), estimate the percentage of families with babies, and figure out the average number of diapers a baby uses per day. Then multiply it all out. It’s not about precision—it’s about clarity and confidence.
Why Canadian Job Seekers Should Care
If you’re job hunting in Canada in 2025, here’s the deal: the competition is fierce, especially in top markets like tech, finance, and healthcare.

Tips to Prepare for Interview Brainteasers
If you’re a Canadian job seeker prepping for interviews this year, here’s how to not get caught off guard:
-
Practice thinking out loud. Even if you don’t know the answer, walk your interviewer through your process. Say things like, “Here’s how I’d start thinking about this problem…”
-
Brush up on estimation. Get comfortable using rough numbers. Whether it’s calculating how many tennis balls fit in a school bus or estimating Canada’s annual coffee consumption, your ability to make smart guesses matters.
-
Don’t panic. Seriously. Interviewers don’t expect perfection. They want to see poise under pressure.
-
Stay curious. Treat every brain teaser like a puzzle. Be playful, not robotic.
-
Practice real examples. Try some classic brain teasers from this Glassdoor list to get comfortable with the format.
