> Google also found that interview performance isn't a good predictor of on-the-job performance.

People repeat things like this without really understanding statistics and priors and what that assertion really means. Assuming that statement is true, it applies only to Googlers who have been hired by the hiring process, i.e. if you are beyond the cutoff threshold of the interview process, the ranking within that subset is not determined by the interview performance. That in no way implies that among all the interviewees, including the rejects, the job performance would not have been correlated with their interview performance, had they been hired, hypothetically.
