Vantaggi
You'll have the opportunity to work with other smart, hardworking colleagues. The problems you'll work on are interesting and challenging. There's a culture of excellence and overall delivering solid technical solutions to problems that require high scalability.
Svantaggi
Some managers are pretty toxic and negative. Your overall experience here will be largely driven by your team, and office politics can play a large role too. Some teams seem great to work on though. With the team I'm on, our manager will focus on assigning blame instead of trying to work collaboratively. It brings down the morale of the team, leading to our team having low productivity, and continuing in a negative feedback loop where the manager blames everyone for not delivering things in a certain way or meeting their unrealistic expectations - even when working 60-80+ hours every week.
