If you ask a single question and get 10-different indirect answers, then the person might be a westerner.
If you get 5-different indirect answers, then the person might be from Indian corporate mafia.
If you happen to read any sane corporate interviews, it might be either from Shiv Nadar or Shivkumar (of Nokia). The reason must be that both are Tamilians. (On a personal note, I strongly believe that only Tamilians and Tamil TV channels have "to the point" discussions/communication).
Having said, I keep following Shiv Nadar's interviews and news (Wikipedia says that he's alumnus of The American College!)... and recently found that he started Shiv Nadar University ... Great story.
