Super niche tweet, but it's remarkable how much information is available about how to become a law professor as compared to when I went on the market <checks notes> 26 years ago.
These days, there's a ton of information out there about the hiring process: Articles, videos, blog posts, podcasts, you name it. Some schools also have channels to help their students and grads navigate the process. There's Sarah Lawsky's annual report, which tells you who got jobs and where. And even at a more basic level, you can easily look up the resumes of assistant profs to get a sense of who different schools are hiring. And if you get a VAP aimed at the market, there's usually a lot of resources to tap and people ready to help you. There's a ton of information.
It was pretty different not all that long ago, at least if I can call my own experience not that long ago (which gets less doable with age, but go with it). I think it was pretty much the norm to sort of learn as you went, maybe getting a quick overview of the process from someone who knew but mostly just going in cold. VAPs were uncommon, so most people were just applying from practice. When I went on the market, I don't think schools had faculty bios on websites yet, so you had to purchase the AALS bios book just to know who taught where. You would write an article or two on your own, try to get them published, and then submit your FAR form and hope for a call. The details of the process were largely a mystery.
A relevant anecdote: I remember going on the market and hearing from a school that was interested in seeing my "research agenda." I didn't know what a research agenda was, as I don't think I had heard of them. So I had to ask around and find out what such a thing was, and then I had to quickly write something up so I could send it to them. I think that was pretty standard. I'm sure there were some people who were plugged in and super informed, but I think most of us were just pretty clueless.
Is it better now or then? It's more rational now, I think: Tenure rates at law schools are high, so getting that entry-level job is often a life ticket. It makes sense that people would prepare for it rather than just sort of wing it. And it makes sense that schools would prefer to have more information for hiring, which probably results from a more prepared applicant pool. But I don't know.
