I am not sure that applies. Introverts and extroverts tend to stand out in groups of people and with people they don't know. We are talking about a team that you should be very close to.
My point is that a lot of engineers I know (irrespective of being introverted or extroverted) would not be comfortable with such a harassing approach. Unless the author used 'look me in the eye' metaphorically as 'be frank with me'.
