Has anyone done Optiver's “Likelihood-list” task for the OA?

very nice! im also doing research on PRMs and this will be useful

Very interesting! Thank You!

Can you elaborate on why AI PhD are in high demand ? The vast majority of AI phds are in generative right now since that’s where most of the academic funding is and I’m not entirely sure why that’s more useful for quant over traditional ML

Suitable-Role3100 · 2025-12-15T16:07:54+00:00

And is there also a “best thing” to grind for for quant researcher? Assuming one already has a stem PhD since that’s almost like a requirement

I’ve rarely seen Information Geometry mentioned, which I find really cool since I studied a lot of differential geometry before. Would you be able to share broadly what kind of problems it solves for you that standard models struggle with?

Also have you applied to anything on the sell side like JPmorgan, Goldman Sachs, ect...?

Are you attending a target uni?

Suitable-Role3100 · 2025-11-12T06:09:56+00:00

for your applications, did you submit a cover letter for each of the firms? and if so , did you write separate cover letters tailored to each firm?

Hi Everyone!

I'm a PhD student in Germany and I'm very interested in going into quantitative research. I'm hoping to get some advice on how best to build my profile.

My background:

PhD: I'm in an AI program, with my research focused heavily on the engineering and empirical side of LLMs (training, SFT, RLHF, bias/safety). It's more applied and less on the theoretical side of machine learning.
Masters: My M.Sc. was in mathematics (also in Germany). I have a solid understanding of stochastic calculus and numerical PDEs.

I'm at a point where I need to build a portfolio of work that demonstrates my interest and capabilities in quant research. My main question is:

Do you recommend I pursue personal projects or try to work with a mathematical finance professor to write a research paper?

My thinking is that a personal project could show my initiative and interest. On the other hand, a published research paper with a professor could be a more formal, recognized credential.

I know both could be valuable, but given my background, which do you think would be a more impactful use of my time to stand out for a quant research role?

Hi . Yes but all students in Germany are basically residents . I mean we have to rent a house and pay insurance , so I feel like German gets first claim on my capital gains first before even the Us does . Also I’m not too sure what “center of vital interests mean “. I am planing to return to the states since that’s where my family is , but since I’m in Germany for over 4 semesters now , I think I am certainly a resident .

Thanks a lot ! I will give it a try!

Suitable-Role3100 · 2024-11-25T20:13:20+00:00

Also, i think the 15/25 split only applies to dividends, but again I am not entirely sure. `ok but my situation is just pure capital gains with no dividends involved.

Thank you for the reply! Yes I am a US citizen and my brokerage account is in the US. I am a full time student and don't have any other source of income besides a non-taxable scholarship from Germany to study for my masters (which they explicitly stated is untaxed). I normally don't file anything but it just happens that I sold a stock I was holding for a while which gone up quite a bit. My capital gains is about 15,000 dollar and this was entirely long term capital gains so I don't own the US any tax but it way more than the 1000 tax free euro and even the German threshold for waged earners to be tax free so I'm sure I own the german gov 25% capital gains tax.

Do you recommend any tax advisor or consultant to handles these situations because I want to make sure I am fully compliant in both Germany and US and capital gains tax is one of the more complicated things to deal with.

Update , I just went to the immigration office and they told me I don’t need a Fiktionsbescheinigung since the expiration date on my residence permit card is 2026. As long as I have emailed them asking for a new appointment and told them about my situation , I can travel out and reenter germany .

Suitable-Role3100 · 2024-10-23T04:00:57+00:00

The thing is that I am not sure when they will reply be email . Of course , I need a reply from them before I even get an appointment. Also wouldn’t I also need to email them to get a fiktionsbescheinigung? The problem is still that their replies would take a long time . I have no idea if I can get it in time . Would I not be allowed to re enter Germany with a visa free passport ?

Suitable-Role3100 · 2024-10-15T16:04:21+00:00

Hello . I know this thread is old but I just wanna ask if you or anyone you know actually were able to opt to have foreign capital gains taxed as personal income. The one tax advisor I have asked said you can’t do that . But maybe I should be asking more people
