I'm a curator of tech interview questions. I'm starting to work with our HR group on a tech recruiting strategy, so I've been looking for more questions. I got an email from a recruiter via a New York Java Meetup group (which is free). The email, of course describes the job requirements, but the best part of the email was the following section:
9 6
4 6 8
0 7 1 5
I had to try to solve the puzzle to see what they did. I tried my first solution, and got my mail bounced back to me... I got immediate feedback from a "unit test." My second solution didn't work either. My third worked... I'm down to 5 lines of Groovy that take about 150 ms.
Yodle had a great job posting. Note: I don't work for Yodle, so if you want to speak with them, you'll have to figure out their culture. On the other hand, if you want a similar culture (at least in part of our HUGE company - SunGard is #380 on the fortune 500), and want to work in a variety of projects, you can always email me. If you can solve this puzzle (and possibly have some finance experience), the interview process will probably just a formality 
.
I'm going to have to work on something like yodle's for SunGard Consulting. We currently have job postings like this, which can definitely use some fine tuning.
<sales_pitch>If you want to hire some consultants who can solve those kinds of problems, you can email me for that as well.</sales_pitch>
