The interviewer, a man who looked like he hadn’t slept since the winter of 2012, leaned back until his Herman Miller chair creaked in a way that signaled either impending structural failure or a very smug question. He didn’t look at my resume, which sat there on the glass table like a discarded napkin. He didn’t ask about the 52 successful campaigns I’d managed or the way I’d rescued a failing product launch in under 32 days. Instead, he smiled with the kind of predatory warmth you usually only see in people who are about to tell you a joke they know you won’t get.

“Why are manhole covers round?”

I felt a sudden, sharp pang in my stomach, and it wasn’t just the intellectual insult. It was the sourdough. Earlier that morning, I’d grabbed a slice of bread, toasted it, and taken a massive, distracted bite while reading an email. It was only after I’d swallowed that I noticed the fuzzy blue-green colony thriving on the crust. That bitter, alkaline taste of mold was now the flavor of my career. I was being judged on a riddle that had been debunked as a useful metric by Google, the very company that popularized it, nearly 12 years ago.

The Cost of Frivolous Cleverness

We are still doing this. We are still asking people to estimate how many golf balls fit in a 742 jet or why a tennis ball has fuzz on it, and we are doing it under the guise of ‘testing problem-solving skills.’ It’s a lie. It’s a parlor trick. Worse than that, it is a specific brand of intellectual hazing that allows the person behind the desk to feel superior while providing zero data on whether the person in front of them can actually do the work. I sat there, staring at him, wondering if I should tell him that manhole covers are round so they don’t fall through the hole, or if I should tell him that his hiring process was a moldy piece of bread.

I’ve seen this play out before, usually with disastrous results. Ivan S., a disaster recovery coordinator I worked with at a previous firm, was the person who actually had to clean up the messes these ‘brain teaser’ hires made. Ivan S. was a man who lived in the details of reality. He once spent 82 consecutive hours in a server room because a ‘high-potential’ hire-a guy who could calculate the angle of a shadow at noon in Cairo in his head-had accidentally wiped a backup drive because he thought the interface was ‘illogical.’

Ivan S. used to say that the problem with hiring for cleverness is that you end up with a room full of people who are too busy being clever to be useful. In his world of disaster recovery, you don’t need someone who can solve a riddle; you need someone who knows exactly which 112-node cluster is failing and has the humility to follow a checklist. Brain teasers don’t select for that. They select for a very specific type of performance-the ability to think out loud in a way that mimics intelligence without necessarily possessing it. It selects for people who enjoy the sound of their own logic. It selects for arrogance.

The Toxic Power Dynamic

“

When you ask a candidate to estimate the number of windows in Manhattan, you aren’t testing their math. You are testing their willingness to play a game where the rules are arbitrary. It creates a power dynamic that is inherently toxic.

The interviewer knows the answer-or at least, they know the ‘correct’ way to guess-and they watch you squirm. It’s a small, pathetic ego boost. It’s a way of saying, ‘I am the gatekeeper of logic, and you are just a supplicant.’

I remember another interview where I was asked how I would move a mountain 12 miles to the west. I spent 42 minutes discussing logistics, environmental impact reports, and the sheer volume of dirt. The interviewer just shook his head and said, ‘I would have just said I’d wait for tectonic plate shifts.’ He thought he was being profound. I thought he was an idiot. We both left that room feeling like the other person was incompetent, which is the exact opposite of what a hiring process is supposed to achieve.

The Grind Versus The Game

But real work isn’t an ‘aha!’ moment. Real work is a grind. It’s the 1422 emails you have to answer to get a project off the ground. It’s the 12th iteration of a design that still isn’t quite right. It’s the patience to listen to a client who doesn’t know what they want. You cannot solve a marketing crisis or a server outage with a riddle about a bridge and four people with a flashlight. You solve it with discipline and specific, hard-won expertise.

If you look at the discussions on Hytale multiplayer server, you’ll see that the most successful people aren’t the ones looking for a magic bullet or a clever shortcut. They are the ones obsessing over the mechanics, the data, and the repeatable actions that lead to victory. They understand that ‘cleverness’ is a fickle friend, but strategy is a reliable partner. In a high-stakes environment, the ’round manhole cover’ answer is irrelevant. What matters is if you can hold the line when the pressure is actually real, not when someone is just asking you a trivia question in a climate-controlled office.

The Disruptive Failure

I eventually answered the manhole cover question. I gave the textbook answer about geometry and safety. He nodded, satisfied, and wrote something down in a notebook that probably cost $42. I didn’t get the job. Later, I found out they hired a guy who had spent 12 minutes explaining why he would make the covers square instead, just to be ‘disruptive.’ That guy lasted 62 days before he was fired for failing to understand the basic regulatory requirements of the industry.

I think about that guy sometimes. I wonder if he’s sitting in another interview right now, explaining how he’d weigh a Boeing 742 without a scale. I wonder if the interviewer is nodding, impressed by his ‘outside the box’ thinking, while the actual infrastructure of the company quietly crumbles in the background.

My mouth still tastes like that moldy bread. It’s a lingering bitterness that won’t go away, a reminder that the systems we trust to evaluate us are often just as decayed as that sourdough. We are obsessed with the wrong things. We are looking for magicians when we need architects. We are looking for riddlers when we need people like Ivan S., who can actually recover the disaster when the clever people break everything.

Ending the Parlor Trick

We need to stop pretending that these brain teasers are a metric for anything other than a candidate’s ability to tolerate a pretentious interviewer. It’s time to throw out the moldy bread. It’s time to focus on the actual, boring, difficult, and infinitely more valuable reality of what it takes to do a job well. Anything else is just a parlor trick, and the world has enough magicians already. We’re all just waiting for someone to ask a question that actually matters, finally, matters.
