Have some good impact, also not crazy skewed in WLB.
Please don't say go to bootcamp and pick.
The day you join you have access to so much information on all the teams, any answer you get here is irrelevant.
You can see all their tasks, their plans, the things they post about, the problems they solve, the jokes they make. You can get charts on how many submissions / SLOC people on the team write. Data on how long it takes to get submissions reviewed.
You can work on tasks from a dozen different teams and get a feel how they work with you. Dozens of hiring managers will want to talk to you 1:1 about their teams. You can physically sit with two or three teams for a week.
So we tell you to go to bootcamp and pick because that is the best advice. It is Engineering Disneyland.
