I didnt want to say this, but I believe your interviewer was
probably subconsciously afraid of you usurping her position, since
you are a young and pretty young lady. She was afraid and jealous.
It would be a different story if the interviewer was male.
Next time, see if your interviewer is a male or female. If it's a
female, before going in, you go toilet first, to mess up your hair
and ruin your makeup. Try to look slightly ugly. Remember, the key
is being un-threatening. If the interviewer is a male, remember to
prune yourself up, and after you go in, cross your legs when you
speak to him. Smile and gaze into his eyes.
This is common sense really.
