I assume by team you mean:  Software development, UX/UI, Design, Tech Support, Marketing, etc. ,right?

YES

That is such a tough question. I’ve worked in all of those. And I often see how one team might not understand something  from another team or could benefit from help from another team. So the inter-team is the most interesting to me.

BUT… if I had to pick one I’d pick the UX Design team because it tends to have a huge affect at least in terms of defining the problem and how we might solve it. I’ve also found UX designers to be very collaborative.

A simple way to answer this behavioral question:

As a PM, I really like to work with Design Team. This is because :-

1. Design team is the ‘closest’ to the actual users and their primary stake-holder in most of the cases are just actual users. So working with them is the next best thing to working with actual users.
2. They are creative and unconstrained. Unlike PMs and Engineers who are constrained by tech architecture, timelines etc ect, designers can go all out and offer amazing experiences to the user. It’s worth working them to develop unconstrained view of things.
3. From learning perspective as well, working with designers help you understand human psychology, do creative thinking, be eccentic about things. All of these things make me learn new things as well as help me grow as a PM.
