Vantaggi
I absolutely love the group I'm on and adore my team members. Everyone is super helpful and ready to answer my questions. I've learned a ton since I started (I'm an intern) and enjoy my project. My manager, mentor, and skip-level have 1:1s with me every single week, to talk about my career goals, issues I might be facing, etc - essentially, the meeting is mine to do with what I wish. Also, working from home is an option - not all the time, since asking questions is way easier in person, but if you need to do so occasionally, they're okay with it.
Svantaggi
There's definitely a pressure to work more than 40 hours a week, so if that isn't your thing, walk away. Also, you need to be self-motivated. No one is going to offer help - you have to ask. Once you ask, though, people are willing to step up.
