Content I've interviewed a lot of people over the last year (Java), and my favorite test is to throw a Stack Trace at them and ask them to figure out what the problem is. The answer is actually quite clear, however. Half of them don't know it's called a stack trace. Some don't know what they're looking at (BYE!). Several focus on the wrong section of proprietary code. Some ask to "open a debugger". however the answer is right there in plain english if you just read the method names. Many don't realize the line numbers are RIGHT THERE, and then start focusing on the lines ending with "Compiled Code". Then there are the ones who work their way up from the bottom, starting with the application container code, and lose their minds. Some who figure out what is happening don't have a solution to prevent it from happening. No, I'm not sharing the trace; suffice to say it's been reviewed by more than 5 of my peers and they all passed. Like Reply 1h Edited I mean, it isn't hard to eliminate people with a coding question. Do you find it impossible to teach people how to read text stack traces, or is this a skill without which they will be unable to do anything of use, or do you just not want to hire anyone? 1 am serious. 1 can come up with dozens of useful programming skills I can test a candidate on that most perfectly skilled programmers would fail. Start with eliminating people who can't code at all. Then find out what they can do that could be useful. If I have 5 people who can already take a printed out stack crash dump, I probably don't need another, and if I do, a qualified candidate can be taught that skill by someone who knows it in under a week. Then again, maybe you work for Stack Trace Inc, and your entire job is looking at stack traces. If so, by bad. Like Reply 22m

Using spaces instead of tabs. You should always, always use tabs, not spaces. 2. Using tabs instead of spaces. You should always, always use spaces, not tabs. 3. Not using auto-formatting. Forget all that tabsspaces rubbish, what's wrong with you - auto-format your code and then people won't have to look at vour weird ideas about brackets and spaces. 4. Using IDEs, which have features such as auto-formatting and nicely- coloured buttons. All code should be written in vi or Emacs, thus ensuring the purity of the programming experience. 5. Not using IDEs. No-one wants to pay for all the time it's going to take you to type things that you could have done at the click of a button, or scroll up and down using some ridiculous key combination invoked using LISP. 6. Failing to learn C and C. It's really important to learn the two absolute essential languages. You think Java is just as good? Fine, write me a real- time control system for racing cars in Java and I'll believe you. 7. Learning C or C when you could be using something modern like Java instead. Admit it - all your schedules involving C or C overrun by five years. And even then the software turns out to have critical flaws that Java would not even have allowed you to create. 8.
