What are your tips to successfully working as part of a dev team?

Hi all!

I am trying to get an idea of what it would be like joining a company and working with other programmers on an app. I have worked in group projects, but small and short projects using free tools like Github Project board. What tools, tips, and tricks do you implement to have successful sprints and cohesion between team members? Have they always worked as you expected?

Thank you for your time!
