Well, where interview requirements reflect actually doing the job, I'd guess the correlation would be significantly higher, no? If interview requirements don't correlate with job performance, I'd conclude the interview process is flawed. After all, the whole point of an interview is to assess performance capability, if it isn't doing that then you need a new process.
