I believe there are 2 ways.

1. Get a professional cert related to the area of banking you wish to enter. Give HR a reason to call u in for an interview.

2. Keep applying, especially contract roles. The shorter the contract, the lower the amount of applicants. This is how i got in, my degree was totally irrelevant to banking but i accepted a 3 month contract to remediate some admin stuffs. Slogged like crazy and completed all the remediation in less than a month. As there are 2 months left, i was helping the team with their BAU stuffs. Someone resigned within the 2 months and i was the no brainer choice to take over in a permanent capacity.
