Will the Solve-the-Riddle Hiring Trend Affect IT? 579

An anonymous reader wonders: "It's probably harder to find a good developer, than for a developer to find a job. Seems to be a Google-riddle trend; rather than caring about references/diplomas/resumes, employers are using solve-this-and-you-have-a-job approach, not even caring about any usual information. Does that give decent graduates/talented unexperienced devs/homegrown coders a chance at the corporate job, or does it alienate potential matches?"

    From the Wikipedia [] entry:
    Some 9,000 people were working at Bletchley Park at the height of the codebreaking efforts in January 1945, and over 10,000 worked there at some point during the war. A number were recruited for various intellectual achievements, whether they were chess champions, crossword experts, polyglots or great mathematicians. In one, now well known instance, the ability to solve The Daily Telegraph crossword in under 12 minutes was used as a recruitment test. The newspaper was asked to organise a crossword competition, after which each of the successful participants was contacted and asked if they would be prepared to undertake "a particular type of work as a contribution to the war effort". The competition itself was won by F H W Hawes of Dagenham who finished the crossword in less than eight minutes.
    Solving a crossword in under 12 minutes was the entrance exam. That's interesting. I remember reading about this in Simon Singh's The Code Book [] in the Chapter on Alan Turing.

    I think the ability to solve puzzles is tightly correlated with the skill set desired by IT. Because it takes an inquisitive and unrelenting mind to hit the hardest puzzles. If they like to do this for fun, surely they can do it well for a living.

    Perhaps it's even more important than the education because of the way IT problems arise? I constantly tell my boss that I complete the crossword everyday at work without fear of repurcussions. I feel this keeps my mind nimble and prepares me for the day.

    Isn't a college degree just a symbol that says, "Look, a whole bunch of people with good reputations threw a bunch of puzzles at me. Some were hard, some were easy, but overall I did well enough to pass through these puzzles. I retained some of the information and processes but that's not really important. What's important is the fact that I'm able to solve problems and paid to do it for four years."

    So, in the end, I predict this will have little or no effect on the IT world at all. In fact, I think it's a better shift towards hiring the most qualified person. For financial reasons, I went to the University of Minnesota but people on the East coast imagine a backwoods podunk frozen tundra instead of an institution of learning when I mention it. If I'm a good puzzle solver, it shouldn't matter.

      You're making too much of it.

      The average network diagram is so convoluted that it can not be accurately put on paper. Having a mind that can actually grasp what's really going on is a rare thing. It's simply another puzzle to be solved.

        You hit the nail on the head there, twice.

        Real IT problems aren't as easy as the Sunday crossword. The problem being that different people are good at different puzzles. But if you're bad at problem solving, it'll show up in your lack of ability to solve puzzles.

        Even our small network here at the office was ugly to diagram out. I was amazed at what a pain it was. And the guy who installed the IP-based phones could not do his job until he drew it out on the whiteboard. We ended up fixing his drawing, then revising it several times as we re-ordered the office a bit for convenience. But we had to draw EVERYTHING for him. With extensive labelling. And we also had to call things by the names he learned in school. It had to be 'FQDN' and not 'domain name' or he'd be lost. (He did eventually figure that one out and start correcting us when we just said 'domain name', though.) He's exactly the sort of 'tech' the puzzles would have made sure they never hired.

        Relying solely upon the puzzles is as crazy as relying on any other single part of the interview process, though. Our office is extremely smooth, and most people get along with most everyone else. A year prior to my hire, the office was not like this. Most people hated coming to work, including the owners. They instituted a personality test during the interview process and things got better quickly.

        Just 1 more thing to help weed out bad apples, that's all.

      Yes and no.

      Out here in Orange County, IGN Entertainment is infamous for their tests. I went in and nailed the interview. The next level to advance to was a test. The test was to implement a small web server (GET/HEAD commands basically) in C++ using *no external libraries of any kind*. They stated the test should take 3 - 4 hours. The specs were extremely vague and any attempt I made to get clarification was met with "do what you think is best".

      They also mailed me the test late on a thursday evening, and were calling asking where it was the following monday morning. Problem being I was currently working 50/60 hours a week as well, and it just happened to be the weekend I was moving :(

      I ask you then, how is anyone who currently *has* a job and perhaps a family supposed to complete a test like this? It seems like the most talented candidates would *HAVE* jobs and therefore find it much more difficult to complete the test. I rushed the program together because -- what choice did I have? It did not represent me well.

      Looking back, the only appropriate response on my part would have been to say "Your requirements suck, and this is not a 3 to 4 hour job. Thanks but no thanks." The entire thing was a waste of their time, waste of my time. Maybe that was the test, to see if I'd tell them to fuck off.

        These kinds of tests usually tell me I don't want to work at that sort of place. If they are going to expect an interview candidate to write a web server in a few hours, then what will they want when you work there? Expect to have demands like 'we need an entire application written this week, don't worry about design or figuring out what the application really needs to do, just write something.'

          Amen, brother.

          I once had an interview where they handed me a few lines of abberent C code and asked what's the output. I answered that it didn't matter, because C code should never be written like that. Production C code should never look like an entry in the Obfuscated C contest.

          That was the wrong answer, of course, and I didn't get an offer, but I figured a sysadmin job at a place that wanted me to be able to read obfuscated C entries probably wasn't the place I wanted to work anyway.

            Of course it was the wrong answer. The ability to analyze a bit of C code (whether or not you think it's "abberent") is an important skill, when determining what a piece of code IS doing as opposed to what it APPEARS to be doing or is DOCUMENTED as doing.

      While I appreciate the unforgiving rock solid logic that is math, asking someone who has been out of math based education for a number of years to prove the irrationality of sqrt(2) is a bit of a stretch.

      I'd much rather go with a series of standardized logic questions (pattern recognition, basic math story problems, etc...) and one question buried in the test that is intentionally vague or poorly worded. Because well defined problems are easy, it's the problems that are not well defined that really test us in IT. Seeing how a potential employee handles themselves in a confusing situation is just as critical as how they handle themselves in a well defined situation. I would stay away from anything that depends on a complex understanding of any given topic, because at this point, we're not looking for someone who has the quadratic formula memorized, we're looking at someone who can look at a situation and pull values from that situation to plug into a formula.

      For those of you confused by the gibberish above, you can solve it by using the key in the subject line. The process involves adding and subtracting each subsequent character value in the key. Since 'm' is the 13th character, you start by adding 13. From there you subtract 15 ('o' is the 15th character), and then you add 15 again. This gives you a final rotation value of 13. You can then apply that to the message to decrypt it.

    Does [solve-the-riddle] give decent graduates/talented unexperienced devs/homegrown coders a chance at the corporate job, or does it alienate potential matches?
    If I do say so myself, I'm a pretty good software architect and developer. However, I don't do well under the kind of pressure typically experienced at a job interview when asked to solve oddball problems in real-time. Often, my biggest insights come when I'm not consiously thinking about the problem, e.g., while in the shower.

    Those who do well at solve-the-riddle interviews are certainly intelligent and can solve problems, but it's not necessarily true that they can solve ill-specified problems -- real-world problems that need solving aren't usually as completely specified as a riddle or puzzle.

    There are other ways to conduct interviews that yield good candidates. Get the person to talk about his past work -- technical people who have done good stuff love to do this with great enthusiasm. You can then ask about trade-offs in thei designs and implementations. You can usually figure out whether the candidate was a key player in the work being discussed.

    Another way is to describe a real-world problem facing your company, but without actually asking the candidate anything. A good candidate will be interested in yoru problem, ask questions, offer suggestions. If the candidate just sits there, s/he's not a good candidate.

      There are certainly tech support jobs out there which consist primarily of what we might call solving puzzles.

      Generally, however, a technical person needs to be broadly competent, needs to have strengths in both analysis and design, needs to communicate well, needs to be able to manage relationships effectively, needs to be able to organize and prioritize effectively under directions which can be incomplete or ambiguous.

      The best technical people are not just able to address the issues in front of them, they use them to generate leverage in making progress toward larger goals. They have to articulate and negotiate for those larger goals, which means they have to be sensitive to interests of other individuals, and to the potential for alignment and conflict among them.

      These requirements hold especially for more senior positions. It's fine to be able to solve puzzles, but that's not most of the job. And as anyone with hiring experience knows, it's far more successful to gain senior people by letting them rise through the ranks than it is to hire them from outside the organization. Unless you make a point of attracting and hiring people who have that potential, you can risk ending up mostly with a whole bunch of puzzle solvers.

      Even scientific research, which obviously tries to solve some very hard puzzles, is mostly driven by collaboration. I've seen generations of compuer science grad students come and go, and the ones that go furthest are invariably the most collaborative. Out of the practice of collaboration they seem to have an easier time understanding their work in context, and they seem able to pick up all the other necessary management skills along the way.

    To submit your resume, you have to construct a URL manually. The Angelides campaign in California is in trouble for doing that on Governor Schwartznegger's "speeches" site, where all they did was to look at the directory of available audio and listen to it, instead of just listening to the stuff that had external links.

    If anybody cares, tle [] gets you to their stupid form.

      And then you have to build up the URL as if some app had built it. The arguments are

      p="auto_submit"&hash="number you get from form page"&referer="URL of form page"...

      There's more, but you get the idea.

    1. Sales has agreed to build a system, and the client's already signed off on a fixed price payment. You have 1 month to build it until the budget runs out. There is no spec, no design document, and no way to confirm any given feature. What do you do?

    A. Build as fast as possible and hope for the best.
    B. Cry and whimper like a baby, because you're completely screwed.
    C. Pitch a fit to management/slashdot/etc about what sales did.
    D. Burn the place down.
    E. All of the above.

    Actually, I got my job that way. Basically, the catch was that they contacted me, and my interest came on when I saw that they used riddles to filter applicants.

    It is a good filter when it comes to separating those who have relevant skills from those who are good at pretending. You can't cheat at "riddles". You can't talk and weasle out of them. You can't impress the interviewer. Don't forget that in HR, few if any people have relevant coding skills. Now, you want to hire a coder. The HR guy hasn't the foggiest what assembler or an export table is, but he should hire someone who can read assembler and understand foreign 80x86 code. How should he do it? Would you rather have the HR guy listen to someone rambling about his "achivements" and qualifications, or do you hand him a paper saying:

    What does this do:

    (together with the correct answer, of course).

    Which strategy do you think will give you the better qualified applicants for the final examination?

      What does this do:
      POP EBX
      INC EBX
      PUSH EBX

      More often than not, crashes the machine.

        Maybe so. A better question might be - Why would you want to use code like this or similar code? On the 65xx, one way of passing arguments to a subroutine was having them embedded in the code stream. So the return address is a pointer to your arguments. You deal with them, then adjust the return address to skip the arguments, push it, then return. So do I get the job???

      You certainly have a right to your opinion. It's great that there's a match between employers who do this sort of thing and people who like that sort of interview. I wrote a web page, Calculating Permutations and Job Interview Questions [] on this topic. What do I suggest for interview questions instead? How about detailed questions about the projects that the applicant has worked on, what exactly they did on these projects, how the solved the problems they encountered, how the software they wrote was st

    ...couldn't get dumber. This is flavor of the week type of stuff, folks. I'm lousy at riddles, but I win design award after design award plus bonuses in my engineering job. I have several patents. I'm sorry, but I just have very little patience for these Grand Unified Theories Of Everything when it comes to dealing with human beings. It just strikes me as HR people looking for ever lazier ways to hire the talent.

    Also, Our IT people have that site blocked. I wonder what that riddle means?

    if you were a manager looking for a wrestler, wouldn't you want to test their physical strength?

    IT is now so much about problem solving, why not test potential employees ability to do just that.
    While it might once have been possible to already know everything about a technology which one was responible for maintaining, that's no longer how the industry works. When there's a new problem, we google. The better problem solver is the better hire.

    I was taken to a conference room, given a hardcopy chunk of code, and told to figure out what it did. On the way out one guy said, "Oh there might be an error in there too". So I did my 'Russell Nash' thing and ran the program step by step in my head and figured the program out. I ran a few more calculations, and I determined there was a problem given a certain numeric precision. The guys came back in about 30 minutes after they left. First they asked to see any scrap paper I used determining the solution. I told them I didn't have any, except for a couple of numbers I wrote on the code pages. They were stunned, but I explained exactly what the program did, which one of them confirmed. Then I explained the error I found. At this point they got very defensive. It seems this piece of code was pulled from their production systems, and "didn't have any errors". I explained what I found to them, and one of them wandered off.

    Oddly I didn't get the job. They said I lacked the ability to document. Funny since I graduated with a degree in technical writing. Maybe they just wanted people to come in an debug for them in interviews.
    • I interviewed for a telecommuting position in a city about two hours away. The Big Project was to re-implement Pointcast or some other stupid push technology, but this time users would actually like it. Yeah.

      So during the interview, they revealed that they were expecting to support about 1,000,000 clients with updates every minute. "Oh?", says I, "how much data are you pushing to each user every minute?" They answered with, "we're very efficient! Only about 1KB." "And how much bandwidth do you have?
