The kind of person who would enjoy working in a strategic alliance organization is one who is able to get along well with people across cultures.
In a strategic alliance, two or more firms work together toward a common goal. These firms may well have very different corporate cultures. Their people may be used to working in very different ways. A person who is wedded to one way of working and to collaborating only with people who work in that same way would not enjoy working in such an organization. In order to enjoy working in a strategic alliances organization, you would need to enjoy working with people who come out of a different corporate culture and who have different ways of working than you do. You would have to be mentally flexible in order to do well trying to crossover between your own firm and the other.
