sure! it depends on the type of law, but if it's not litigation, then a lot of it is going to be (1) advice/counsel and (2) legal documents and other paperwork.

(1) a big part of any attorney's job is basically helping their clients understand the law. whether the client is an individual or a company, pretty much any attorney is going to get "can i do X" ("can i legally fire this person" "can i use a trust to keep my kid from paying taxes on the gift of my house passing to them on my death") and "how can i do Y" ("how can we avoid getting sued for this doctor signing their name on a patient while they were under anesthesia" (real one i saw btw)) etc questions from their various clients. they take questions from their clients, research if needed, and then outline what the client can and can't do, and how they should or shouldn't do it. sometimes this is done simply or email or a call, and sometimes it involves writing legal opinions (formal memos) with citations etc.

(2) documents/paperwork - whether it's wills for my practice area, which can also extend into working with the courts after someone passes away because we do their probate (executing the will or helping their family do so), drafting contracts or policies for someone in a corporate law or general counsel position, working out merger agreements for an attorney who works in mergers & acquisitions, drafting deeds in real estate and making sure they are recorded where needed, etc. it's the full life-cycle of drafting the document, reviewing and revising (incorporate client's desired changes where possible), negotiating changes with any other legal parties/counsel involved, making sure all those changes are kosher legally and cover any possible scenarios they need to, coordinating it getting executed, making sure it gets shared or recorded wherever it needs to be, and safely storing the electronic and original copies. so like "doing paperwork" sounds simple but there's usually a lot of steps for any single document, and for a lot of things any action is going to have multiple documents involved too. there's... a lot of paper, even for firms that don't maintain real paper files anymore. (in early 2000s a lot i knew of had full paper files that included print outs of literally everything included all draft versions and emails, but these days most of them only keep original executed documents and everything else is electronic. but it's still a LOT of paper.)

pay: this seriously depends on where you're located, what tier the firm is, and what level attorney you are. a first-year associate in a medium-sized city will probably be making under $100k. trying to pay off law school with that... 💀 but if you're an equity partner at a biglaw firm you might be making like, $400k per year. but that takes years and years. i really don't think it's worth it if money is all you're interested, but it's definitely a bonus if you're genuinely interested.

for your other question: i've had some rude attorneys but i don't really recall working with any like Traditional Jerk types who act like assistants are coffee-runners lol, just that they can be more brusque/gruff and particular. i do think working with attorneys means you need to roll with different personality types and not take anything too personally. you have to have like customer service voice AND ALSO backbone to redirect them when appropriate lol. whenever i interview, firms want someone who can keep attorneys in line. so you can't be rude back, but i can definitely be like "well, i will call (person/department who actually does that) for you :)" (but most of the ones i have worked for have been very nice and that means i WILL do the minor personal stuff like that for them because they treat me well and ask nicely)

i hope that was good info for you!!
