Realistic shots for HF internship

Dear all,

I am currently doing my Master's in quantitative finance at a respectable university in Continental Europe and this summer I will be doing an IBD summer internship in a top group at a tier 1 bank in London. From next year January on, I would like to combine my Master's thesis with an internship at preferably a (very good) hedge fund.

My question is, would I stand a chance to obtain such an internship at a prestigious HF? (e.g. Citadel, Brevan Howard, Bridgewater) Furthermore, what would be the best way to get an interview, given that they do not recruit on my campus and often have no HR or a website?

Thanks in advance lads!
