IQ test scores are massively correlated with workplace performance.
I find it plausible that among the set of people Google has hired grades don't predict workplace success, but I bet if Google were to randomly select employees from among the U.S. population (or even from just among computer science majors) grades would be hugely correlated with performance.
I'd be curious to see that research that proves IQ test scores are correlated with workplace performance. All jobs or just some? How strongly correlated? How is workplace performance measured? Is it discussed in your book?
A good starting point might be this 2004 review by Schmidt & Hunter. It tabulates correlations of 0.23 to 0.58 between "general mental ability" and "supervisory ratings of job performance", with the correlation increasing monotonically with a five-level rating of job complexity.
Edit: I should probably add Schmidt & Hunter's note that those averages "are corrected for measurement error in the dependent variable and for range restriction but not for measurement error in the GMA measure; hence, these are estimates of operational validities, not construct-level correlations."
