Ask HN: Would you solve programming puzzles to apply for jobs?
9 comments
It'd be cool, but there are a few things to worry about:
- Bugs in the system are dangerous; for instance, if I did my quiz in an hour but it got submitted as two, my job opportunity could be lost
- People will get around your anti-cheating methods
- People will practice or memorize solutions to your quiz (while there's no problem with practicing, this allows people who are good at solving your quiz but bad at programming in general to get through)
- Code comparison may not be useful, especially since a lot of tasks will lend themselves to being expressed in just a few ways which most code will use
- Defining a useful metric for "how good your code is" is tricky, possibly impossible
It'd be especially good if your quizzes asked for things that needed to be implemented anyways. It'd be a nice, cheap way to build up an open-source code repository.
Honestly, I'd probably do the quizzes just for fun. Now that I think about it, something similar already exists which I do play for fun: http://projecteuler.net/
Altogether, it sounds like a good idea if you can get the details right.

Something like this already exists: TopCoder. They are pretty well known and have a good reputation, so they will be hard to compete against. With that said, however, there are a lot of things that can be improved: (like what you hinted at) you can have each company submit their own problem and make it more open, etc. If you are going to run with this idea, good luck!
Does TopCoder have a job posting feature? I can't find it.
Strikes me as pretty easy to game, as Google's MY friend... Might have some use for hiring fresh-from-school, but anything more senior's best done by reputation rather than brain teasers. True rockstars would not stoop to proving it - imagine asking Linus to play such a game.
Who knows? He might do it, if it's fun.
It sounds like a good idea, but it probably would only work well for junior programmers. I'm working on something similar in a couple ways, but not related to programming.
But assuming I figured out a way to make it hard to game
I hate to sound discouraging, but when it comes to job interview techniques, making it hard to game is the entire problem, not just a detail.
This is true, but I don't want to describe the details in public which would only make it easier to game. I am just wondering if hackers would use the service if it was available.
If the quizes you pass happen to be the type that a company wants to post a job for, the site will let you know that you should send in your results for consideration since the job might interest you.
This system would be completely language-independent since as long as the generated result set is correct then the code is assumed to work and someone at the company will review your code in more depth anyhow.
Assuming the obvious cheating methods are stifled with sophisticated code comparison techniques and google searches, thus making the system difficult to game and relatively fair, is this a site you guys would use?
If not, why not? Thanks for your feedback!
