I suggest you could
1. Explore more on the industry suggested and find out more details on these careers
2. Speak to someone who are working in these industries if you know any
3. Find out summer intern opportunities to work in these industries. The corporates/banks/account firms may post the opening on their website. If there is any corporate that you have high interest on, you can consider to send an email to their HR to seek opportunities.
4. Sometimes, these corporate may hold campus recruitment session. You can also join to acquire more information
