He is an awful person IMHO. However, he has been interviewing for 25 years and never had anyone walk off his stage during an interview. Being that she is the only one and he asked a reasonable question, she is 100 percent at fault on this one.
BTW, he doesn't really have 25 years experience ~ he has 1 year of relatively poor interviewing and did it 25 times.
Guy is a dud.
