If you are having trouble getting internships for finance, finding a job as a corporate lawyer isn’t going to be any easier.
You usually have to go to a top 14 law school, at least top 20, to have a good chance of getting a corporate law job. The market is already saturated with lawyers whereas there is a high turnover in entry finance jobs.
The most immediate steps you can take are maintaining a 3.7+ overall gpa and getting a good LSAT score. Maybe join mock trial or something. Also talk to corporate lawyers to see if it’s right for you. It’s going to suck to be saddled up with $200k in law school debt only to find out that you can’t get a job or hate law
