I'm in that line, join banking sector.

First step is to choose the correct company to onboard.
Strongly suggest to joint Banking IT sector, software house - banking or IT advisory.

Anyway welcome onboard to IT world

Here are the paths you can potentially take.

1/ Work at a bank - But you need to find a bank which has their own in-house development team if you want to practice your coding and development skills
2/ Work at a software house - Basically you work at a company which provides softwares to banks, they can be a core banking provider, AML, fraud detection, payment gateway, clearing houses and many many more
3/ Work at a Fintech - This would be the most fast paced type role as well
4/ Work at a digital bank - This probably has one of the more better options as now we already have 3 digi banks launched and 1 more coming soon.
