Find the right fit career for you

I've noticed so many people (especially as they get into their 30s) are not sure what they want to be doing for a career besides knowing they don't want to stay at their current role. I'm thinking of something like a quiz based system that can hone in on roles that would be a good fit for you even if you don't know what they are. There are plenty of roles out there many of us have never heard of so how can you know if you'd enjoy it or succeed if you don't know it exists?

So a high-level example would be if your results show that you are analytical and enjoy sales, maybe a marketing analytics role would be a good fit. Then provide the user with some job descriptions for such a role as well as key skills they need to succeed (Tableau, SQL, Google Analytics, etc). In this way you

1. Get a better idea of what roles would fit you
2. Find out what skills you need to succeed
3. Through #1 find what communities you need to network with
4. Through #2 you can take online courses to learn them and add to your resume
