May I ask why you left finance for tech? I'm considering going into trading instead of SWE because the environment may be more social. I also spend a lot time analyzing current events, so why not get paid for it, too?
That's not to say that people in that industry can't be charming - they totally can be, but they will also do whatever it takes to boost up their reputation (and therefore their annual bonus) at your expense. "Liar's poker" is a pretty accurate description of the culture, but it's much worse when you have to deal with it every day.
My experience was on the sell-side, things may be different on the buy-side. Feel free to message me if you want to chat.
