How to get hired as a Business Intelligence analyst in the UK? (Graduate Role/entry level)

I'm 25M a recent graduate with masters in computing, I graduated in July 2024 and have been applying for jobs afterwards, I don't have any experience in my field except a remote internship that I did in the UK. I was working as a student worker in the Uni and also worked in Argos, I've been trying to learn Power BI by myself and l'm also working towards IBM BI analyst cert on Coursera. I've participles in a few challenges one with FDM group and other with Kubrick. I'm not specialised in a specific IT field as l've mostly navigated my way through various experiences. (I moved to the UK two years ago as a student and now am in the process of getting my graduate visa which will last for 2 years). Currently l've been doing a bit of food delivery to meet my expenses and I've been really struggling to keep applying for jobs at the same pace as I was doing just after graduation as I was only working in Uni part time, but now l've more expenses but everything is getting better as l'm trying to save up a bit also taking a gap with application process has probably boosted my confidence a bit I think, ik it sounds strange, but the issues l've been facing in the past are that although I'm generally quite confident even in class setting and everything, in the interviews l've not been able to really sell myself. I've had a few interviews in different areas like procurement, HR role and some business intelligence roles but they were mostly for councils, the only really technical one l've been in was with UKRI. Now I'm putting all my energy to apply for graduate roles. Business Analyst or intelligence analyst roles etc. I would really like some advice from people especially from the UK who are familiar with the culture and everything. Sorry for the rant any advice would be appreciated.
