Stereotype means someone hold some extreme views with another person because their relationship have been very bad or they'd got disagreements with each other. But actually these views in that kind of situation wasn't right.
I believe that if anyone has any prejudice or stereotype will affect make decisions. For example, if you are a interviewer but you has prejudice or stereotype with the guy who is interning with you then the results will not be real. So let's be honesty with anyone and be real with anybody.
