Who is using coding assessment for technical interviews?

[supratims]

Anyone using a real code repository for assessing candidates' ability to code, run tests etc as part of a technical assessment ? I would like to know what kind of problems are you using. Any success ?

We used to ask candidates to code the http://rosettacode.org/wiki/Fibonacci_sequence in a module, plus tests for the first 10 numbers.
