Effective remote collaboration is essential in the era of globalization, with leadership, knowledge transfer, and interruptions playing critical roles in team dynamics and performance. However, research on these aspects in remote software development teams remains limited. Our study investigates how leadership styles emerge, how knowledge transfer impacts performance, and how interruptions influence engagement in remote software teams. We conducted a 2-hour study with 30 developers, organized into 3-person teams working on programming tasks in a controlled virtual environment, followed by individual retrospective interviews. Our results revealed that democratic leadership was prevalent in the teams, with frequent communicators perceived as leaders. Teams that shared more knowledge and were selective in what they engaged with were more successful, while interruptions reflected team engagement rather than disruption. Our findings highlight the importance of developing leadership skills and improving collaboration tools for remote software teams.
