Thomas Edison's Eccentric Job Interview Questions: A Cheat Sheet

Hulton-Deutsch Collection/CORBIS
Hulton-Deutsch Collection/CORBIS

Thomas Edison had an encyclopedic memory, and by the early 1920s, he had become increasingly frustrated by the fact that college graduates applying to work for him didn’t have a wealth of knowledge comparable to his own. To test the mental mettle of incoming job seekers, he administered to each a series of 150 questions, tailored to the position for which they were applying. Some were specific to the industry, while others were mysterious. Masons, for instance, needed to know who assassinated President Lincoln.

Others were topical (In what cities are hats and shoes made?) and are now outdated (What telescope is largest in the world?). But just in case the Edison Quiz fad ever returns, here’s a cheat sheet to help you master some of the finer points. Good luck!

Who was Francis Marion?
An officer in the Revolutionary War, often cited as being the father of guerilla warfare. His skill at clandestinely moving troops by dressing drably and utilizing swamp paths earned him the nickname “Old Swamp Fox.”

Where is the River Volga?
Oh, the longest river in Europe? Russia, of course.

Who invented logarithms?
Scottish mathematician and ruff-wearer John Napier, in the mid 1600s. He also combined the work of Italian mathematician Fibonacci and Ottoman genius-of-all-trades Matrakç? Nasuh to invent the awesomely named “Napier’s Bones,” an abacus-like system of numbered rods that transform multiplication, division, and exponents into simple addition and subtraction.

What is the first line in The Aeneid?

Arms, and the man I sing, who, forced by fate
And haughty Juno’s unrelenting hate
Expelled and exiled, left the Trojan shore:
Long labors, both by sea and land, he bore;
And in the doubtful war, before he won
The Latin realm and built the destined town,
His banished gods restored to rights divine,
And settled sure succession in his line;
From whence the race of Alban fathers come,
And the long glories of majestic Rome.
-- Virgil, and translated by John Dryden.

Note: The colon after “shore” is disputed, so we include the entire first stanza for good measure. Playwright George Bernard Shaw would have correctly answered this one, as evidenced by the title of his 1894 play Arms and the Man.

What war material did Chile export to the Allies during the War?
Sodium nitrate, which was used to manufacture gunpowder, and made Chile very rich. Nitratine appeared there in such large deposits, the mineral is also known as Chile saltpeter.

A question tailored to cabinetmakers: Who was the Roman emperor when Jesus Christ was born?
Caesar Augustus, Sept. 23, 63 BC—Aug. 19, 14 AD.

Where is the Sargasso Sea?
The only “sea” to be entirely surrounded by water, the Sargasso is actually an elliptical patch of the North Atlantic, near Bermuda. The water in this area is relatively calm and thick with seaweed (sargassum weed, actually), trapped there by the surrounding currents: the Canary Current at the northeast, the Northern Equatorial Current along the south, and the Gulf Stream on the northwest.

Because of the Sargasso’s relatively low precipitation, high evaporation, light winds, warm temperatures and high salinity, scientists used to think it was a sort of oceanic desert; they knew aquatic creatures made their habitat in the sargassum, but thought the water wasn’t hospitable to plankton. More recently, however, mysterious plankton blooms suggest that the area is “far more productive than we could explain...” according to Dennis McGillicuddy, oceanographer and leader on the Eddies Dynamics, Mixing, Export, and Species composition (EDDIES) project. Put that in your pipe, Edison.

Of what is brass made?
Brass is an alloy of zinc and copper. Humans started making brass as early as the Neolithic era, though ancient texts often use the term brass when they mean bronze – an alloy of copper and tin.

Who was Leonidas?
The military king of ancient Sparta who heroically led a mere 300 men in the battle against massive Persian forces in the battle of Thermopylae. Sure, he had some help from other Greeks, but the 300 thing is his legacy. So much so, he’s now most famous for being the guy who yells “This! Is! Spartaaaa!”

Who discovered the X-ray?
The obvious answer to this question is Wilhelm Röntgen, who, in 1895, famously noted the effects of a mysterious new kind of ray that appeared as a byproduct of his experiments with Crookes tubes. He called his discovery the “X ray,” to indicate its yet unknown properties, then went on to take a widely publicized X-ray print of the bones of his wife’s hand, and eventually won a Nobel prize in 1901 for his achievements. However, several other physicists made similar discoveries while experimenting with Crookes tubes around the same time. Among them: Nikola Tesla, Edison’s well-known rival. Edison had himself experimented with X-rays for a time, and was certainly aware of the variations in the X-ray origin story among his colleagues. This question suggests an eagerness to promote his preferred version.

Where do we get shellac?
You probably know shellac as a term commonly applied to wood varnish, which is actually a combination of alcohol and the naturally occurring thermoplastic resin also called shellac. But did you know the latter shellac is produced and secreted by the lac insect (Laccifer lacca), a type of scale bug somewhat related to aphids and cicadas? Proper shellac is also used commercially in products like sealing wax, hairspray, and even cake glazes and anti-caking agents in candy. Vegans beware.

Why is cast iron called Pig Iron?
Modern-day metal workers would argue that cast iron and pig iron are not exactly the same thing, but what Edison probably meant by pig iron was the raw material used in making iron and steel. Back in the day, pig iron was melted into casts that resembled baby piglets suckling from their mother. Likewise, iron workers used to call the iron in the adjoining lateral channel “the sow.”

Who was Bessemer and what did he do?
Henry Bessemer invented the Bessemer process, which revolutionized mass production of steel. From pig iron. See? We’re learning!

Pencils Down!

Of the well over 500 young men who took Edison’s test, only about 35 passed to his satisfaction (a score of 90% or higher). When several disgruntled rejects complained to the press, Edison refused to release his questions and answers, so the public had to rely largely on the memory of his “victims” for the complete list. Magazines subsequently began running “Edison pop quizzes,” and rival employers -- fancying themselves as exclusive as Edison -- began conducting employment quizzes of their own. Edison’s scientific conclusions on the subject?

“Only 2% of the people think, as I gather from my questionnaire.”

The Only Way to Answer ‘What Is Your Greatest Weakness?’ In a Job Interview

Thanks in part to the influence of Silicon Valley and its focus on the psychological probing of job applicants, interview questions have been steadily getting more and more abstract. As part of the interview process, today's job seekers might be asked to describe a vending machine to someone who’s never seen one before, or plan a fantasy date with a famous historical figure.

Even if the company you’re approaching isn’t fully on board with prodding your brain, at some point you may still come up against one of the most common queries applicants face: "What is your greatest weakness?"

"Some 'experts' will tell you to try and turn a strength into a 'weakness,' to make yourself look good," writes Inc. contributor Justin Bariso. "That advice is garbage."

"Think about it," Bariso continues. "Interviewers are asking the same question to countless candidates. Just try and guess how many times they hear the answers 'being a perfectionist' or 'working too much.' (Hint: way too often.)"

While responding that you work too hard might seem like a reliable method of moving the conversation along, there’s a better way. And it involves being sincere.

"The fact is, it's not easy to identify one's own weaknesses," Bariso writes. "Doing so takes intense self-reflection, critical thinking, and the ability to accept negative feedback—qualities that have gone severely missing in a world that promotes instant gratification and demands quick (often thoughtless) replies to serious issues."

Bariso believes the question is an effective way to reveal an applicant’s self-awareness, which is why companies often use it in their vetting process. By being self-aware, people (and employees) can correct behavior that might be affecting job performance. So the key is to give this question some actual thought before it’s ever posed to you.

What is your actual greatest weakness? It could be that, in a desire to please everyone, you wind up making decisions based on the urge to avoid disappointing others. That’s a weakness that sounds authentic.

Pondering the question also has another benefit: It prompts you to think of areas in your life that could use some course-correcting. Even if you don’t land that job—or even if the question is never posed to you—you’ve still made time for self-reflection. The result could mean a more confident and capable presence for that next interview.

11 Behind-the-Scenes Secrets of TV Meteorologists

The first weather forecast to hit national network television was given in 1949 by legendary weatherman Clint Youle. To illustrate weather systems, Youle covered a paper map of the U.S. in plexiglass and drew on it with a marker. A lot has changed in the world of meteorology since then, but every day, millions of families invite their local weatherman or weatherwoman into their living room to hear the forecast. Here are a few things you might not know about being a TV meteorologist.

1. SOME PEOPLE JUST NEVER MASTER THE GREEN SCREEN.

On-camera meteorologists might look as if they’re standing in front of a moving weather map, but in reality, there’s nothing except a blank green wall behind them. Thanks to the wonders of special effects, a digital map can be superimposed onto the green screen for viewers at home. TV monitors situated just off-camera show the meteorologist what viewers at home are seeing, which is how he or she knows where to stand and point. It’s harder than it looks, and for some rookie meteorologists, the learning curve can be steep.

“Some people never learn it,” says Gary England, legendary weatherman and former chief meteorologist for Oklahoma’s KWTV (England was also the first person to use Doppler radar to warn viewers about incoming systems). “For some it comes easily, but I’ve seen people never get used to it.”

Stephanie Abrams, meteorologist and co-host of The Weather Channel’s AMHQ, credits her green screen skills to long hours spent playing Nintendo and tennis as a kid. “You’ve gotta have good hand-eye coordination,” she says.

2. THEY HAVE A STRICT DRESS CODE.

Green is out of the question for on-air meteorologists, unless they want to blend into the map, but the list of prohibited wardrobe items doesn’t stop there. “Distracting prints are a no-no,” Jennifer Myers, Dallas-based meteorologist for KDFW FOX 4 writes on Reddit. “Cleavage angers viewers over 40 something fierce, so we stay away from that. There's no length rule on skirts/dresses but if you wouldn't wear it to a family event, you probably shouldn't wear it on TV. Nothing reflective. Nothing that makes sound.”

Myers says she has enough dresses to go five weeks without having to wear a dress twice. But all the limitations can make it difficult to find work attire that’s fashionable, looks good on-screen, and affordable. This is especially true for women, which is why when they find a garment that works, word spreads quickly. For example, this dress, which sold for $23 on Amazon, was shared in a private Facebook group for female meteorologists and quickly sold out in every color but green.

3. BUT IT’S CASUAL BELOW THE KNEE.

Since their feet rarely appear on camera, some meteorologists take to wearing casual, comfortable footwear, especially on long days. For example, England told the New York Times that during storm season, he was often on his feet for 12 straight hours. So, “he wears Mizuno running shoes, which look ridiculous with his suit and tie but provide a bit of extra cushioning,” Sam Anderson writes.

And occasionally female meteorologists will strap their mic pack to their calves or thighs rather than the more unpleasant option of stuffing it into their waistband or strapping it onto their bra.

4. THERE ARE TRICKS TO STAYING WARM IN A SNOWSTORM.

“In the field when I’m covering snow storms, I go to any pharmacy and get those back patches people wear, those heat wraps, and stick them all over my body,” explains Abrams. “Then I put on a wet suit. When you’re out for as long as we are, that helps you stay dry. I have to be really hot when I go out for winter storms.”

5. THERE’S NO SCRIPT.

Your local TV weather forecaster is ad-libbing from start to finish. “Our scripts are the graphics we create,” says Jacob Wycoff, a meteorologist with Western Mass News. “Generally speaking we’re using the graphics to talk through our stories, but everything we say is ad-libbed. Sometimes you can fumble the words you want to say, and sometimes you may miss a beat, but I think what that allows you to do is have a little off-the-cuff moment, which I think the viewers enjoy.”

6. MOM’S THE AUDIENCE.

Part of a meteorologist’s job is to break down very complicated scientific terminology and phenomena into something the general public can not only stomach, but crave. “The trick is … to approach the weather as if you're telling a story: Who are the main actors? Where is the conflict? What happens next?” explains Bob Henson, a Weather Underground meteorologist. “Along the way, you have the opportunity to do a bit of teaching. Weathercasters are often the only scientists that a member of the public will encounter on a regular basis on TV.”

Wycoff’s method for keeping it simple is to pretend like he’s having a conversation with his mom. “I’d pretend like I was giving her the forecast,” he says. “If my mom could understand it, I felt confident the general audience could as well. Part of that is also not using completely science-y terms that go over your audience’s head.”

7. SOCIAL MEDIA HAS MADE THEIR JOBS MORE DIFFICULT.

Professional meteorologists spend a lot of time debunking bogus forecasts spreading like wildfire across Twitter. “We have a lot of social media meteorologists that don’t have necessarily the background or training to create great forecasts,” Wycoff says. “We have to educate our viewers that they should know the source they’re getting information from.”

“People think it’s as easy as reading a chart,” says Scott Sistek, a meteorologist and weather blogger for KOMO TV in Seattle. “A lot of armchair meteorologists at home can look at a chart and go ok, half an inch of rain. But we take the public front when it’s wrong.”

8. THEY MAKE LIFE-OR-DEATH DECISIONS.

People plan their lives around the weather forecast, and when a storm rolls in, locals look to their meteorologist for guidance on what to do. If he or she gets the path of a tornado wrong, or downplays its severity, people’s lives are in danger. “If you miss a severe weather forecast and someone’s out on the ball field and gets stuck, someone could get injured,” says Wycoff. “It is a great responsibility that we have.”

Conversely, England says when things get dangerous, some people are reluctant to listen to a forecaster’s advice because they don’t like being told what to do. He relies on a little bit of psychological maneuvering to get people to take cover. “You suggest, you don’t tell,” he says. “You issue instructions but in a way where they feel like they’re making up their own minds.”

9. DON’T BANK ON THOSE SEVEN-DAY FORECASTS.

“I would say that within three days, meteorologists are about 90 percent accurate,” Wycoff says. “Then at five days we’re at about 60 percent to 75 percent and then after seven days it becomes a bit more wishy-washy.”

10. THEY’RE FRENEMIES.

The competition for viewers is fierce, and local meteorologists are all rivals in the same race. “When you’re in TV, all meteorologists at other competitors are the enemy,” England says. “You’re not good friends with them. They try to steal the shoes off your children and food off your plate. If they get higher ratings, they get more money.”

11. THEY’RE TIRED OF HEARING THE SAME JOKE OVER AND OVER.

“There’s always the running joke: ‘I wish I could be paid a million dollars to be wrong 80 percent of the time,’” Sistek says. “I wanted to have a contest for who can come up with the best weatherman insult, because we need something new! Let’s get creative here.”
