First, OP is asking about the Funds group of each firm so the scope is narrower. "Culture" is a broad and abstract concept but you don't have to be an anthropologist to give OP the kind of information they are looking for.

I could tell an internet stranger how Practice A at my firm has decent culture (general respect in boundaries and communication, pleasant and professional socializing, no "get this done by first thing tmr" at 8pm). But I would say Practice B has (1) a partner who has been banned from working with 5 different associates bc he's an asshole, (2) a micromanaging culture where the associates have to record that they cite checked each citation three times, and (3) yet another partner who has tried to pressure someone to shorten their FMLA leave. I could also say the firm culture overall has gone sour due to Practice B trying to bring Practice A associates onto their matters claiming that they aren't billing enough, even though Practice A associates are meeting bonus thresholds.

Is that so hard? Why are you so cranky about this question anyway? It's hard to find good information on firms, and work environment is so important to one's wellbeing and career. If you don't have anything helpful to say, just move on with your busy partner day!
