Why Are Manholes Round? The 10 Toughest Interview Questions
A job interview at one of Google’s 75 campuses around the globe might seem to have more in common with pledging a secret fraternity than job-hunting. An often months-long interview process, iron-clad non-disclosure agreements and back-to-back hours of interrogation in windowless offices are a matter of course, but the added intrigue of allegedly absurd interview questions takes the experience into cloak-and-dagger territory.
Why are manhole covers round? How do you measure 4 gallons of water using only a 3 and 5 gallon jug? How many gas stations/dogs/windowpanes are there in the US? According to career community Glassdoor.com,these are a few of the more obscure queries asked of wannabe Googlers.
You have to give it to them, the questions are creative. But are they effective in finding the right candidate? And more importantly, will answering them correctly land you a job?
“This kind of question is used to determine poise and the ability to think on one’s feet,” says Dale Austin, director of career services at Michigan’s Hope College. “But also to assess creativity and problem-solving.” In other words, Google is looking for a quick answer that proves you’re not only agile but logical, adaptable and math-minded.
That’s all well and good for the analytical minds of Googlers, but veteran Bay-area executive headhunter Chuck Pappalardo says it really all depends on what you’re looking for. For Google, whose ranks Pappalardo describes as “engineer from top to bottom,” they can prove telling. “These kinds of questions measure whether someone can work in the crazy environment [of a young tech firm] and have the right engineering background to make them a good employee. They show quick, analytical thinking, and the ability to pivot.”
But what these “trick” questions can’t highlight is a quality that Pappalardo sees as not only more human, but more vital to the majority of careers–positions where customer or client interaction is essential. That quality? Integrity.
“A good interview requires more than just good questions. It also requires a deep understanding of the traits and behaviors you’re seeking or avoiding,” he says. “By crafting questions designed to elicit “evidence” of the desired characteristics, you’re able to draw conclusions about candidates’ ability to perform in an authentic and meaningful way.”
Fine, if you’re on the questioning side of the desk. But for those of us in the hot seat, prepping for questions designed to “elicit characteristics” can be quite tricky. Pappalardo concedes they can be among the most difficult to answer, because they require much more than rattling off resume points. Here, the 10 toughest—but most telling– interview questions, and best of all…how to answer them.
1. Why is there a gap in your work history?
“Employers understand that people lose their jobs and it’s not always easy to find a new one fast,” says Susan Nethery, the director of student affairs marketing at Texas Christian University, who often advises recent grads on the interview process. When answering this question, list activities you’ve been doing during any period of unemployment. Freelance projects, volunteer work or taking care of family members all let the interviewer know that time off was spent productively.
2. Can you think of a recent problem in which old solutions wouldn’t work?
This question is seeking a creative answer. The interviewer is trying to identify how knowledgeable you are in today’s work place and what new creative ideas you have to solving problems. Ex: Your workplace swears by fax machines for signing contracts. Until the phone lines go down. Did you save the day with a scanner and an emailable .pdf? You may want to explore new technology or methods within your industry to be prepared for. Twitter-phobes, get tweeting. Stat.
3. What would the person who likes you least in the world say about you?
“The people who can’t answer this question are the people I worry most about,” says Jim Link, managing director of human resources at staffing firm Randstad “I can honestly say I’ve never hired one of them.”
Link says that this tricky question, a twist on the “what’s your worst quality or weakness?” standby, often leads to pregnant pauses as the interviewee struggles to present an answer that won’t present them in a bad light. “I’m not saying answer it quickly, because you should definitely answer it thoroughly.” Highlight an aspect of your personality that could initially seem negative, but is ultimately a positive. His example? Patience—or lack of it. “Used incorrectly this can be bad in a workplace. But always driving home deadlines can build your esteem as a leader.”
4. What is the biggest risk you’ve ever taken?
“Some roles require a high degree of tenacity and the ability to pick yourself up after getting knocked down,” says Dale Austin, director of career services at Michigan’s Hope College Providing examples of your willingness to take risks is important because it not only shows your ability to fail and rebound, but also your ability to make risky or controversial moves that succeed.
5. Have you ever had a supervisor challenge your behaviour? How, and how did you manage that?
Pappalardo shares an anecdote from an interview he recently conducted. “The head of IT was rolling out a new technology to the sales team that required two days of training. He wouldn’t back down despite sales pushing back saying they couldn’t make time for it. Finally the president of the company challenged him about his actions, forced him to rethink his stance. He was a senior executive standing on propriety, not creativity.” In the end, Pappalardo says the executive rebounded and a compromise was reached—but it’s the lesson learned, not the situation, that the interviewer is looking for.
6. Describe a time when you were part of a project or planning team that could not agree…
Lynne Sarikas, director of the career center at Northeastern University’s business school, stresses that questions pertaining to difficulties in the past are a way for potential employers to anticipate your future behaviour “by understanding how you behaved in the past and what you learned.” It’s important to clarify the situation succinctly, she says, to explain what specific action you took to come to a consensus with the group and describe the result of that action.
7. If you could change one thing about your last job, what would it be?
Beware oversharing or making disparaging comments about former coworkers or supervisors, as you never know what bridges you may be burning. But Taylor warns that an additional trouble point in answering this query is showing yourself to be someone who can’t vocalize their problems as soon as they arise. A good rule, she says, is to steer clear of people. Problems with technology are safe ground.
8. Explain a database in three sentences to your 8-year-old nephew.
This frequent Google question is no trick, and Taylor says it can be tailored to any sector. “Explaining public relations, explaining mortgages, explaining just about anything in terms an 8-year-old can understand shows the interviewer you have solid and adaptable understanding of what it is they do.” Do your homework, she says, “Know the industry and be well-versed.”
9. Tell me about yourself…
Seems simple, right?
It’s not. “This is difficult because people tend to meander through their whole resumes and mention personal or irrelevant information in answering,” says Dawn Chandler, professor of management at Cal Polytech’s business arm. Jana Fallon, a VP of staffing and recruitment for Prudential, agrees. “Keep your answer to a minute or two at most. Cover four topics: early years, education, work history, and recent career experience. Emphasize this last subject. Remember that this is likely to be a warm-up question. Don’t waste your best points on it. Keep to your professional career! (e.g., don’t cover your family life, weekend activities, pets, collections, etc.)
10. Why should we hire you?
The most overlooked question—and also the one most candidates are unprepared to answer. Chandler suggests that this is often because job applicants don’t do their homework on the position, and as a result aren’t able to pinpoint their own unique qualifications for the job. What they are really asking is why you are more qualified than everyone else. “You need to review the job description and qualifications very closely to identify the skills and knowledge that are critical to the position,” she says, “and then identify experiences from your past that demonstrate those skills and knowledge.”
