First of all, I'd like to say that you're giving a really good question. When it comes to jobs, careers, interests, a better question for me would be, " what you haven't tried? " because guess what? I have tried quite a lot of things!
Right now I'm about to be hired in a big company, but I don't like big, structured companies. However, the one in which I'll be working as a developer will have a startup culture and really friendly atmosphere, so not only I'll be able to take initiative and responsibility, I'll also be able to to pursue different interests at the same time. Is it my dream job/career? Not at all and here's why:
1. I'd like to work on my own ideas, dreams and ambitions, therefore I see myself in the future working for myself. This will act as a good stepping stone though.
2. I don't believe in team spirit. I'm more of a " do it your own way " kind of guy.
3. Even though I enjoy the company of other people and I like being involved with others, I still require some privacy and there I won't have much of that.
Is it linked to my passions? Well, I love learning and studying, so I'll be able to do that just fine. Also, It will be required of me to take initiative and more responsibility, so I'll be more than happy to challenge myself.
