When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

PIDFILE=/var/run/$NAME.pid | |
#This is the command to be run, give the full pathname | |
DAEMON=/usr/local/bin/bar |
#!/bin/bash | |
# herein we backup our indexes! this script should run at like 6pm or something, after logstash | |
# rotates to a new ES index and theres no new data coming in to the old one. we grab metadatas, | |
# compress the data files, create a restore script, and push it all up to S3. | |
TODAY=`date +"%Y.%m.%d"` | |
INDEXNAME="logstash-$TODAY" # this had better match the index name in ES | |
