Yes, I believe perception is skewed due to how people categorize their experiences:

If someone speaks perfect English, gets all the in-jokes and is in general great to work with, you'll think of them as a "team member", even if they happen to be from India. But if someone has problems with the language, doesn't get the jokes, and/or has a vastly different timezone, you'll remember them as distinctly "Indian".

That means if someone asks you to remember experiences with Indian coworkers, you might be more likely to recall the people that didn't work out well, because they stood out more strongly.
