As commonly implemented, it’s certainly a less-skilled job with a lot of banal repetition, tedious procedure, and not much scope for or need of original thought.

As one familiar with the Indian education system (which is heavily rote-based and does not generally encourage understanding-based learning, especially before the tertiary level) and the mentality it produces in comparison with the western mind, I would say (and please don’t misunderstand me; I’m making a dispassionate assessment of why it might be so, not whether it should or should not be so) that this is actually a pretty good match, and it would not surprise me—nay, I would expect—to find Indians and especially Indian women fitting in better into that style of QA department than into other fields such as development; and when you have a large fraction of people who think in such-and-such a way, it will tend to be self-reinforcing and -perpetuating. (This is also a significant factor in why these sorts of effects in how you think as a whole have a habit of lingering for a generation or two after transplantation into another country.)
