    These types of riddles provide no reasonable basis for determining anything relevant to the job nor the interviewee's ability to cope with such situations.

    I don't tolerate riddles in interviews simply because it happens too often where the interviewer expects the interviewee to struggle with it until the little "gotcha!" is revealed. Useless! I understand the point of the riddles is different, but my experience (and seemingly the experience of many others) shows they are not generally used in a manner that might allow to glean a bit of information about the interviewee.

    If the person can't be civil about the situation, then yes, the person has issues and you're lucky to have detected them early. But it's entirely possible the person will merely stand and extend a hand for you to shake while saying "I'm sorry to have wasted your time. Goodbye." Not because the problem is unsolvable but because the question suggests the interviewer is silly which in turn suggests the company is silly.

    Whenever I sit down for an interview and the interviewer starts off with a brain teaser question, I politely interrupt them and say, "I understand why you are asking this sort of question, but I feel it is very important that I get an accurate impression of the type of work you will expect from me as well. Could you please take a few moments to explain the (project, problems, technical issues, etc.) first and then continue where we left off?".

    If this throws the interviewer off, it's a HUGE red flag to me in that it implies the company is not really thinking about finding the right person for a job, or the job itself is not well defined.

    Nobody has mentioned hats yet -- as I recall, that was how most of the 900 original comments got started. (Red, blue, three, can't see own hat, how do you choose?)

    I remember being in the middle of this nightmare on the OP. Curiously, or perhaps cretinously, it inspired me to buy the book "How do you move Mount Fuji?" which deals with precisely these questions and a lot of interesting Stanford-Binet history besides.

    This had unfortunate effects.

    Dim Bulb Interviews 2.0 hit me the very next time I interviewed after reading the book, at a Prestigious Financial Institution in the hell-hole of the universe (read London). They had both kinds of questions there: country and western.

    The "western" (Richmond) type was an incessant barrage of Fujiesque stupidity. I breezed through all of them with ease, right up to the one with two lengths of fuse that aren't even, but burn through in an hour. How to time 45 minutes? This is where I made the classic interview error.

    "I've read the Fuji book and I can answer all the questions, even the pirate one (which I think relies on an unsound application of induction) and the one with the goblin in the middle of the lake. I've got a mental block on this one. Do you have the book handy?"

    Bad move. Bad move.

    But not as bad as my answer to the "country" question, asked by a spotty twenty-two year old *nix freak fresh out of college.

    El Spotto: "What would you use 'cut' for?" Me: "Nothing."

    Not quite sure which one lost me a job I would have loathed, really. Don't care, either. Have been watching their stock price decline ever since, with the sole intention of glorying in Schadenfreude.

    LED bulbs do not generate heat - what kind of light bulbs are we talking about? riddle for the riddler.

    Bright LEDs emit heat -- that's why you need heat dissipators near them...

    OK, it's not as bad as with the usual "we heat up some wolfram(?) fiber to get heat and therefore light with just 3% of the powerinput converted to light, but even with 10 or even 30% efficiency there's still quite an amount of heating the air involved. Just assume you want to get the same "amount" of light as with a 3% incandescent (3W of "light" in a 100W incandescent) you'd need a 10W LED (or equivalent of smaller LEDs) at 30% efficiency to replace it (ideal conditions, etc) so it will still get quite warm if left "burning" for a longer time. Hey, even my USB DVB-T receiver is gets notably warm if watching TV for some time - and USB is no more than 2.5 Watts (5V, 500mA).

    Of course if you talk about a childs toy with three 20mW red LEDs...

    According to my 30 seconds of googling, the first method is too unreliable, and from reading this thread , all planes have a logbook of weights and are regularly plopped on scales, so the obvious answer is correct. The fun part is that the common curveballs (what if you don't have a scale?) are easily met with "The plane doesn't fly due to safety concerns".

    My comment has only the most vaporous (or vapourous, if you prefer; or we could just go with "tenuous") of connections to yours; but you sparked a memory. I can tell you how to move Mount Fuji, because I've done it.

    Well, okay, it wasn't Mt. Fuji, specifically; it was a mountain in Hermitage, Tennessee, in another life (circa 1974). A bassist friend and I had moved there to sell ourselves as a duo -- bass and drums -- and as luck would have it, they were building a new highway within walking distance of the apartments we rented (it takes a while to get established in the music biz in Nashville). So we hired on as heavy equipment operators, a field in which we both had some experience. We worked a deal with the foreman that as long as they had work for us, we could work on the highway between gigs, and then take off on the road when we got work with a band.

    My friend Jack drove a Cat #9 dozer, and I drove a pull (or scraper, or earth-mover; I think the names for those things are regional). And we literally moved a mountain into a valley. Jack and another dozer were positioned at the top of this mountain, and me and about five other pulls drove up one side and were pushed down the other side until our cradles were full, and then we bounced and careened our way down the slope and into the valley, where we dumped out our loads and went back up for more.

    It paid, if I recall correctly, $3.82 per hour, which was a livable wage for the place and time. We worked there off and on for about five months, until I found out my wife was pregnant with our first child, and I decided to take up a more dependable line of work.

    I drove back through there again a couple of years back. Tried to find those same apartments, but they were gone. I did see, though, that they succeeded in getting the rest of that mountain moved, even without my help. How 'bout that.

    vt_mruhlin:
    If your job routinely pushes you out of your comfort zone, you need a new job. The economy is kind of bad right now, but it's still easier to change jobs than it is to change comfort zones.

    And if you "enjoy being pushed out of your comfort zone", then you by definition haven't actually been pushed out of it.

    If you're hiring in a situation where you know that occasionally you and your employees will have to work outside their comfort zone, why wouldn't you want to try to separate the people who would respond with something like "hey, this is new and interesting, I've never thought about this sort of stuff before" (and even be motivated by the novelty) from the people who would get annoyed about how "this isn't in my job description!" or the like?

    Sure, you can claim that the people in the former group are then not, technically, out of their comfort zone when confronted with with the novelty, but frankly that's fairly irrelevant. But if you insist, look at it this way: you're trying to find people whose comfort zone includes a high tolerance for novelty and an interest in a wide range of things. And that's a good thing, if said traits are applicable to the job being interviewed for. To dismiss the usefullness of such questions/problems out of hand is just as silly as to use them in an interview for a mundane, routine job where they would be irrelevant.

    Of course, it does seem fairly common to see people taking the "if some of it is good, a lot of it is better" approach and instead of asking diverse/unorthodox---yet still practical and appropriate---questions, going to ridiculous extremes with inane trick questions where there's only one "right" trick or questions that rely on familiarity with a few particular pieces of obscure knowledge even though that knowledge has no relevance to the job at hand. (I suspect that another reason a lot of people like those is so that they can feel superior about knowing the trick while the interviewee flounders in confusion, and those people are jack***es through and through.) But unexpected stuff happens a lot in life, and someone who would walk right away if they didn't initially see how a question could be relevant to the job is someone I'd want a lot less than someone who'd have enough interest in the unusual to stick around to see just how it was connected.

    3. carry the fat one across. Then get 2 new friends; leave one just in case they ask you about how fast you have to run away to be safe from a bear.

    if you are ever stumped, just answer that the shape prevents it from falling down the manhole because no matter which way you place it in the hole, the cross section is always the same. 9 times out of ten this will answer any job interview question.

    Complete agree on the programming test. Where I work, everybody goes through a 2-3 hour programming under somewhat realistic conditions (i.e. you're left alone, have access to the web, etc). These tests are relatively simple and not brain teasers (we don't expect anybody to write a solver for Soduko in 2 hours).

    While I initially scoffed at that idea, after a few years of being on the interviewing side I find the input from these programming tests extremely valuable.

    You have no idea how many folks with "years of industry experience" sit in that conference room for two hours, remove a few lines here and there from the skeleton that we provide them and did not add a single line of code.

    Brainteasers on the other hand, I find fairly useless, since they usually do not represent any realistic conditions that you tend to encounter as a soft-developer.

    There are infinitely many shapes that will not fall through the hole. Any regular polygon with enough sides (at least 10 should do) would be unable to fall down the hole due to the lip on the cover, and you could even do silly things like cutting notches out of a circle. Even if you only allowed an infitesimally small lip, you could still use a pentagon with rounded sides, similar to the Rouleaux triangle—actually, any odd-sided polygon would do.

    Separately, on another interview a while back, the guy asked me to write a program to display the numbers from 1-100 in a printed matrix, along with some other info. Then he lets me at his computer to write the program. And leaves the room while I do it (don't get me started on this one). No biggie. He gave me an hour. I finished in 5 minutes. I even put a nice little header on it to indicate what each column meant. The guy runs the program and pipes the output directly through wc -l and tells me it's wrong because the line count is wrong. I tell him to just run it without piping it. He sees the header and says "But I didn't tell you to print out a header". At that point, I tell him I'm not interested in working for someone who so myopically micromanages, and walk out.

    I need to start asking that question so I can weed out people like you. Specifications exist for a reason, such as preventing problems when output is piped into another program that doesn’t expect a header. I’m sure the team will be really happy when their system doesn’t work (or worse, gives wrong outputs) because someone idiot didn’t follow the agreed upon specifications. I’m sure they’ll be even happier when they need to waste a couple hours tracking down what is causing it.

    As long as you specify that it's meant to be piped into another program. Implicit buttumptions just make an butt out of people.

    Then again, that's clbuttic gold-plating so you can tell he's a real programmer :P

    Such silly puzzles basically serve to weed out the people who do not perform well under that specific type of look-over-your-shoulder-breath-down-your-neck-solve-it-now-while-I-watch-you sorts of "pressure". In 20+yrs of software development, I've never once had to do real work in any such environment. Software development "pressure" is more about schedule/quality stress, not about solving puzzles while we watch you with a microscope. There's a whole class of people, and I count myself as one, who are perfectly good developers and architects, but who work best in a let-me-think-it-through-in-peace sort of environment. I once interviewed at Microsoft as a contractor, told the manager, in advance, that I didn't do well with interview puzzles, and invited him to give me a programming problem to solve in a day. I took it back to work, solved and programmed the solution over my lunch hour, emailed it back, and got hired. My years at M$ were very productive and enjoyable, and all made possible by an understanding interviewer/manager who recognized that good developers come in many flavors, and are not to be weeded-out through artificial, idiotic, interview-induced puzzle-solving pressures.

    My first thought, oddly enough, was the water-displacement method. Methinks that would be awfully hard on the aircraft however, especially if the engines were running. Hmm, should we consider the keep-it-dry constraint? How about the advantages/disadvantages of saltwater vs fresh? How will barnacle accumulation during weighing be accounted for? Would this be a stripped-bare plane, or one fully-outfitted for a Saudi Arabian prince?

    No, no, no, this isn't about practical solutions, this is just "so we can see how you think". We don't want someone who can coolly mull over all the facets of a problem, determine the possible approaches and their respective strengths and weaknesses, and come up with an appropriate and practical solution.

    I've been asked to write code on whiteboards in interviews -- it has some merit, but no one really does this anyway, you think about the problem, get some ideas, look at some docs, write some code, run, test, debug, repeat...

    The last several interviews I've given, I've given the candidate my laptop and some mocked-up data and asked them to write some simple programs in the language of their choice. This has done a good job of weeding out the ppl who can write code from the ppl who can talk about it. And you get to see if they can solve problems, think of corner cases before they encounter them, and handle the small things that most of us do day-to-day...

    Q: There's a production bug in the code that's affecting X and costing us money every second. What do you do? A: Talk to Dev Lead. Reproduce and try to fix it. Check logs, check the code, check the db, etc. Show solution to Dev Lead.

    Q: They don't do anything, what do you do? A: Talk to their manager.

    Q: They don't do anything, what do you do? A: Try to find someone to listen.

    Eventually saying that I wouldn't bother trying anymore, which didn't seem to go over well, but I don't see how there's another answer. I mean if their tact was that nobody gave a crap, then why would I? Who am I to presume that I know better than they did.

    I even asked what sort of answer they were looking for, and they didn't know how to answer that. They gave the 'it's your approach that matters' ... so I guess communication with the team I'm in, trying to fix the problem, and escalating to superiors was the wrong approach. Silly me.

    Spanky:
    I've been asked to write code on whiteboards in interviews -- it has some merit, but no one really does this anyway, you think about the problem, get some ideas, look at some docs, write some code, run, test, debug, repeat...

    Yes, I agree completely. Whiteboarding is only useful for kicking around possible approaches/solutions to problems.

    The last several interviews I've given, I've given the candidate my laptop and some mocked-up data and asked them to write some simple programs in the language of their choice. This has done a good job of weeding out the ppl who can write code from the ppl who can talk about it. And you get to see if they can solve problems, think of corner cases before they encounter them, and handle the small things that most of us do day-to-day...

    As an interviewer, you yourself are not thinking of the corner cases. The corner cases in the form of developers who don't think/code well while under the hot interrogation lamp of an interview. They may be superb developers, but are corner-cases that you're going to miss out on simply due to your interview techniques.

    Most of us do our day-to-day work in relative privacy in an environment that we create for ourselves that is conducive to thinking and problem solving. For some, that may be listening to AC/DC at full blast while working the problem. For others it might be kicking back at Starbucks for a couple of hours, espresso in hand, working it out. High-pressure, artificial puzzle-solving/coding interviews only serve to weed out people who may be ultimately some of your best problem-solvers.

    Riddles are a great way to eliminate the large number of people who can't even adhere to three or four basic requirements. Go read the comments for the original version of this article and you'll see what I mean.

    I could just get a fish-scale type scale and grease the wheels and measure the force required to displace the mass... F=ma, do the math^H^H^H^Hphysics.
