Either she has never been taught how to project the appropriate body language or she was so nervous that she forgot everything.Ok I better rephrase, her head language was interesting.
I think she should have gone to the toilet before the interview.
She was also unprepared, but that may be the same problem.
I felt that while vaguely answering the Q, she was more interested in promoting the company.
The head and eye movements were unforgivable from a management PoV. And made her appear untrustworthy
Her posture was similar to leaning forward into a propped up phone for Whats App. Surely not.
On that performance, she's not destined for the top.
And yes, I've studied body language.
