Get candidates to read code
I've interviewed a lot of people for various positions, and obviously been through more than a few interviews myself. Looking back on all of these interviews and the companies and projects involved I found the following:
The CV is the candidate's introduction - It's relevance is to show the breadth and depth of their knowledge and experience and also whether they can write properly in an organised way. It gets them the interview, nothing more.
If the organisation puts an excessive emphasis on the need for previous specific experience, and it's not for a particular project, run for the nearest exit regardless of whether you're the interviewer or interviewee. It means that organisation is either already living in the past or doesn't have a clue - either way the role and the organisation is doomed to stagnation or failure.
The interview is to tell you whether the candidate can fit with your team and oganisation. Use the candidate's references to check your intuition after the interview is over.
Get your candidates to read some code, in some language not related to anything on their CV. Get them to tell you what they think it does and whether it has any bugs. Give them access to the web for this. If they can't pull together a reasonable answer in half an hour, then they're only good for positions that require a lot of hand-holding and supervision.
