It&#x27;s a very difficult situation.  I know we spend a lot of time discussing this on HN, but I&#x27;m glad we do, this really is one of the biggest issues facing our industry.  We (software developers) essentially have to study for and pass a comprehensive whiteboard exam almost every time we apply for new job.  Alternatively, we may have to spend up to a day or more on a &quot;take-home&quot; exam.<p>I do think that Gayle Laakman McDowell (who wrote &quot;Cracking the Coding Interview&quot;) has written a couple of good posts on this topic.<p><a href="http:&#x2F;&#x2F;www.gayle.com&#x2F;blog&#x2F;2015&#x2F;6&#x2F;10&#x2F;developer-interviews-are-broken-and-you-cant-fix-it" rel="nofollow">http:&#x2F;&#x2F;www.gayle.com&#x2F;blog&#x2F;2015&#x2F;6&#x2F;10&#x2F;developer-interviews-are...</a><p>It&#x27;s a pretty good roundup of the various interviewing approaches, and the problems with each.  I have some differences of opinion, but I agree with the overall point, which is that there really isn&#x27;t a great way to do this.  The in-person coding exam (I don&#x27;t like to call it an &quot;interview&quot; because I really do think it is more reasonable to call it an exam) at the whiteboard may not be the worst of a bunch of bad choices.<p>Here&#x27;s my main problem with all of this - it is extremely unpleasant, developers clearly don&#x27;t like it, employers acknowledge that it has a very high false negative rate… yet seem to see no connection between this and their own constant complaints about a &quot;shortage&quot; of software developers.<p>I do see my friends in other industries interview, and they don&#x27;t go through anything like this.  Lawyers, doctors, nurses, and actuaries (among others) certain do take exams, but they take those exams under much more controlled circumstances, where well understood degree programs and study paths prepare you for the exams you will be taking (even so, many people describe these exams as the most stressful academic experiences they&#x27;ve gone through).<p>All in all, I do think that this practice deters people from becoming software developers, staying in the field, or changing jobs.  It&#x27;s one of those things that makes individual sense for a single employer, but in aggregate takes a heavy toll on the field.<p>I do think some kind of highly respected professional accreditation could solve this problem (actuaries, for instance, must pass a rigorous exam on vector calculus, linear algebra, differential equations, and so forth), but I&#x27;m guessing that senior actuaries don&#x27;t have to do a tricky integration by parts during an interview.  Devs most definitely do.  Then again, I fully recognize that &quot;professionalization&quot; does come with serious risks (with a few edge case exceptions, anyone who wants to become a lawyer has to go through three years of law school at $100,000+ cost, and many many people feel this is excessive and is really there for regulatory capture&#x2F;cartel building).<p>Again, there&#x27;s no perfect answer.  My only thing I can say with real conviction is that companies that engage in this kind of interview exam, accepting that it is stressful and produces a high false negative rate, really need to stop scratching their heads about the &quot;shortage&quot; of good candidates.  I find that a little hard to take.  I accept that there are good reasons to do these exams, but you must understand the role you have played in your own shortage when, by your own admission, your process weeds out lots of good candidates.<p>And one other thing - whatever the process, employers should not look for ways to push the inefficiencies of the interview process out onto the candidate.  Although I just didn&#x27;t study enough for my google interview exam (and who knows, I may not pass even if I took 6 months to study),  Google clearly spent the valuable time of its own engineers to interview me.  I&#x27;ve done a take-home exam where I spent 8+ hours, and honestly, I received so little feedback I have no idea if they even read it, it was a one-line brush off <i>a full month later</i> (&quot;we&#x27;ve decided not to proceed with your application at this time.&quot;).<p>Another good post from Gayle McDowell on this one:<p><a href="http:&#x2F;&#x2F;www.gayle.com&#x2F;blog&#x2F;2013&#x2F;09&#x2F;18&#x2F;companies-who-give-candidates-homework-assignments-knock-it-off" rel="nofollow">http:&#x2F;&#x2F;www.gayle.com&#x2F;blog&#x2F;2013&#x2F;09&#x2F;18&#x2F;companies-who-give-cand...</a><p>That I won&#x27;t do anymore.  It has cost me some opportunities, but I do sort of feel we need to make some kind of stand as a &quot;profession&quot; (it is very difficult to make this stand as a scattered collection of individuals, which is why I put &quot;profession&quot; in quotes).
