How do people judge a contestant in a Miss India or similar beauty contest?
By the way she looks, talks and carrys herself, it is after all a beauty contest.
How do the decision makers judge a lady in a tech industry where she does not need to interface or meet with any customer on a day to day basis?
The right answer: By speaking to her, understanding her knowledge of the technology, how it works, who handles the tech aspects
The obviously incorrect way : Put her under surveillance without her knowledge for years, have a few people stalk her and judge her solely on the way she looks, dresses and talks to non tech persons, without ever giving her a chance to defend herself directly. Nothing is ever done openly, because the people who do so do not have the guts to admit their harassment of a single lady.
