In US, you mostly hire for specific roles....developer, or QA or some such thing, even if straight out of college. Most colleges here are good..you can trust the grades to about 75% accuracy. In India, in college recruiting, your plan is to hire relatively bright people and train them later. And you don't trust the college's grading. For this purpose, you also conduct an aptitude test. If they pass a cut-off mark, then you consider them for a programming interview or for in-person interview.
