Got a 2:2 in maths from Imperial - what should I do?

I graduated this year from Imperial College with a 2:2 in Maths - I had personal issues during my last year and soon after arriving at university I realised I had zero interest in the purer side of university mathematics (I got borderline 2:1s in my previous years). I did enjoy some of the modules that I did in 3rd year but clearly didn't do well enough.

I have pretty much no experience either. I had applied to some summer internships in mainly quant/S&T and gotten a few interviews (got past OA for Optiver, DRW, etc, Hirevues for the bulge bracket/middle market banks), but ended up nowhere. It was a big mistake of mine not to apply for more roles.

Now with a 2:2 with no experience, I just feel somewhat lost and I'm wondering what sort of stuff I should be looking for. I've applied to some offcycles and grad schemes in markets/S&T/asset management to places without a strict 2:1 requirement though I doubt that I'll get anywhere. I've also applied to some other stuff in accounting/tax/audit/big 4 etc, but I kind of just dread working in that field - just feel like I'll end up working a job that I'll hate there. At the same time, I know beggars can't be choosers, and it's important to keep my options open.

Any advice would be greatly appreciated. Thanks.
