That's a tough interview question?! Ha! I was asked this one while applying for an electrical engineer position:
The riddle was, "you have 9 coins of the same size. One of them weighs more than the rest. Using only a balance, how do you identify the heavier coin in the least number of weigh-ins?".
I got the answer after a few minutes. It can be accomplished with 2 weigh-ins.
The answer is to separate them into 3 stacks of 3 coins. Then you weigh two of the stacks. If the stacks balance, you know the 3rd stack has the heavier coin. You then put one coin from the third stack onto each side of the balance. If those coins balance out, you know the remaining coin is heavy. If one of the stacks in the first step is heavier you know that stack has the heavy coin and you continue to the second step to weigh that stack. #googleinterviews
I'm going to be honest and say that as a junior at an undergrad business school studying marketing and working on startups, those questions were about what I'd expect from Google...and honestly, the ones she posted weren't tough (although when you're under that much pressure, even a basic arithmetic problem can seem daunting). *edit* Actually now that I think about it, they're much easier than what I'd expect from Google.
I translated that whole article as "My inability to perform basic math functions and think logically wasn't good enough for Google, but it's good enough for Business Insider." #googleinterviews
I actually think I would do quite well with the more off-beat questions they asked. Although, Those kinds of questions simply cause me to ask more questions. It would only be a matter of time before I was asking more questions than the interviewer. #googleinterviews
I had an interview one time for an inter-company transfer when I was working for a large insurance company.
Most of the questions were boilerplate, but then, the manager tosses out, "What would you do when the rabid wolverine we keep in the closet escapes?"
Without missing a beat, I responded, "I'd throw mashed potatoes at it, because everyone knows they love orange juice."
I was able to say it with a straight face and he continued on as if the question and answer never happened.
I ended up getting the job. A few weeks into it, my manager told me it was that answer that got me the job. Everyone else got flustered and stumbled over their response, or asked him to repeat himself. I was the only one to just toss anything out there. He wasn't looking for an answer...he was looking for a reaction to an unusual situation.
Although, he did admit he liked my response.
In the corporate world, sometimes it's not what you know, it's how you do it. I was interviewing for a critical job in the data center, and had to make snap decisions on the fly. Sure, they weren't all that critical, but, I proved I could think on my feet.
So, enjoy your unusual questions. Sometimes the interviewer is an idiot, but, most likely, there is a good reason for asking them. #googleinterviews
I wonder what they're looking for. First question about the golf balls, for example: My initial thought is, duh, one golf ball could easily fit in a school bus. They didn't say "maximum number" of golf balls, and I have to assume these questions are meticulously designed.
But the reader suggested answer demonstrates an entirely different way to go about answering the question (based entirely on assumptions and guesswork).
I wonder what kind of questions they ask when they're interviewing for an industrial organizational psychology job?
Something like, "How many seemingly strange questions does it take to cause a interviewee to mentally break down?" #googleinterviews
It's called the "case method" of interviewing, and it sucks. Interviews for consulting firms like Bain & McKinsey use this method....you have to practice for them, because getting used to thinking in certain ways, using some key figures at the outset are the key to answering these questions.
I once interviewed for Bain....I got the to final round and was asked two case questions. The first was "how many pieces of mail does the US postal services process every day." Somehow, i nailed it, and actually got to a number close to the actual number (although i don't remember exactly how i arrived at it). The second case was about an airline company where I was given a couple of facts and was told to give my reasoning why the company was losing money. I asked all kinds of questions to see if I could find out something that would indicate the problem, but at the end of the day, I didn't hit on the exact reason Anyways, didn't get the job. oh welllll. that was 5 years ago. #googleinterviews
@AlphaPepper: This is generally true but doesn't really apply to Google.
At Google just about everything is done by engineers/developers or people with that mindset. Sometimes even basic decisions are made using algorithms rather than design or marketing knowledge.
Many designers/marketers find this concept horrifying, but it often works quite well for Google. They can push out a variety of different solutions to different customers, and then use the one that works the best in the end. #googleinterviews
@AlphaPepper: But, I would seriously doubt the intelligence of someone who could not answer that particular question that they asked her. Granted, interviews are stressful situations, but when you're interviewing 50 people for the same job, you can afford to drop the people who can't handle the pressure. #googleinterviews
My father went pretty far through the interview process with them before being turned down because he "didn't fit in with the culture" On one occasion, I walked by when they were phone interviewing him and they were having him code out loud over the phone. #googleinterviews
meh. they aren't all that interested in your answers, only at how you arrived at them. except the math stuff, which was pretty basic, even if she was blindsided a bit. their process is arguably brutal, but at least they aren't ambiguous about what it is they are looking for. they didn't get to where they are by hiring people just to be nice.
when it comes down to it, though, i'd rather work for apple.
@Hello Mister Walrus: To be fair, no one's really thinking clearly during a high-pressure job interview. It was good of the guy to giver her time to respond.
While we're being fair, the "I vowed to switch to Yahoo for life" was childish, moronic, and frankly if I were Google, that alone would confirm I shouldn't have hired her. Sorry, toots. Looking for a job is tough business. You don't get to start your own little boycott at every rejection. And a high-profile company isn't evil just because the interview is hard. That's how they get high-profile. #googleinterviews
Having been on the support and production side of the product food chain for years, I'm totally heartened to see potential marketing candidates have to do a bit of actual work. #googleinterviews

"How many times a day does a clock’s hands overlap?"
You really have to ask the clarifying questions, like does the clock have a second hand?
If so, does it count as a 1 or two overlaps when all three hands intersect? #googleinterviews

"Maybe…$70,000?"
Something tells me that it wasn't that the questions were hard, but this person wasn't being particularly bright at the time. #googleinterviews
