Software Engineer at Google Nest Devices & Services team

Asking for a friend. A friend is doing a team match right now with the aforementioned team. This team is involved with writing b2b and b2c services for the nest devices. My friend would like to know about the team culture and growth opportunities in the team. If someone here has known the team, it'd be great if you can share some information about the nature/difficulty of projects handled by this team. Thanks.
