Organizations like team players. Even though some mobile developers will readily admit that they work best on their own, organizations prefer developers who are good at collaboration. This is because application development is a synergistic process, and the more input from different people with varied backgrounds, the more robust the application is likely to be. Of course, at some point during the application development process, the functions and features need to be locked in, and input from many developers can have a negative impact. Interviewers will expect you to have perspectives on when collaboration is effective and when it isn't.
