Nope. If they are given about 3 hours to cook, I find they are softened enough (use higher heat if the duration will be shorter). That's not to say you can't pre-fry them or something if you want to!
I should have mentioned that I usually make my chili vegetarian. In the rare occasions where I do add meat, I will pre-cook that, but it's mostly because of paranoia and because I don't own a cooking thermometer.
Since you're not sure what you want to do, I say don't pursue a specific career, but pursue a field that interests you. You might not have the luxury of finding a job opening for exactly what you want, even if you did have something specific in mind, but by having relevant skills you can get closer and eventually find something that works for you.
I went to school for a certain field, found a job that was in no way related, and eventually got a position there that did use my education (I was chosen because of it). 10 years later, found a new company in "my field" that uses both my education and the skills from the previous job that I thought would never be useful elsewhere. The more things you can put on your resume, the better, especially in a world where AI will be screening thousands of applications for the most keywords.
