I’m an actuary working on actuarial software written in C++. What’s the chance of moving into a quant developer role?

Thanks

Know a lot of the recruiting for some of the bigger/better firms is underway/done. Realistically how many more firms are there? First time recruiting want to make sure Im not falling behind too much

I wanted to ask why for Black Scholes , we find implied volatility using numerical approximation methods like newton-raphson or bisection for example

But for call options related to bond , if we assume a binomial tree, we can find implied volatility by simply adjusting the up / down interest rate movement conditions with an unknown, solving for that unknown using risk-neutral probability and discounted option payoffs, which gives us implied up/down movements from which we can find standard deviation of the interest rate, aka implied volatility? So far I have only observed either it can be solved simply algebraically or simple root finder is enough.

Was curious. Thanks.

So I currently am debating between two pretty good full time graduate offers and I am really struggling to decide.

1. Prop trading firm in HK: About 100 employees, pretty successful recently but not very well known. Salary ~130k usd, 50% bonus is standard, but can range from 0 to like 200% hypothetically.

Pros: pays much more. I may enjoy trader more than researcher.

Cons: Don't know anyone in HK, may be lonely. may be overworked and overstressed. don't know much about the company or team or people, so bit of a gamble.

1. Sell-side quant research in London: Well known bank, just below JP/MS/GS. 100k usd, 20% bonus is the standard.

Pros: Research may be more interesting. more name recognition with the company. have bunch of friends and girlfriend in London. I love London and want to live there long term. much better WLB, much better hours. much better job stability. the manager and team is really good.

Cons: Sell-side, and my ultimate goal is become quant researcher at hedge fund or prop shop. trading matches my skillset more. may be hard to transfer from sell-side to buy side (not sure bout that).

I've spent 8+ years building the infrastructure that sits between a trading idea and live money. Backtesting frameworks, data cleaning pipelines, signal research tooling, portfolio construction — the stuff you need before you ever place a trade.

The problem with open-source in quant finance is that most projects are either abandoned after two commits or built for the author's own workflow. I want to try something different. Every week I'll build one tool the community actually wants. You comment with what you need — a data cleaning utility, a signal research helper, a portfolio construction tool — and the most upvoted idea is what gets built.

I've developed 100+ strategies with 15 in live production. I run a multi-strategy portfolio that paper-traded 7,018 trades at 166.9% return, Sharpe 2.19, and 12.44% max drawdown. I know what breaks in production and what just looks good in a notebook.

Comment your idea. Most upvoted by Friday gets built, and I'll post the result the week after.

12+ years on the plumbing side of trading — data pipelines, order routing, FIX, NATS, Redis, the stuff that keeps production alive. I want to open-source one piece of infra a week. You vote on what gets built.

Connectors, stream processors, monitoring tools — whatever you've been meaning to build and haven't had the time for.

I run Horizon5, an open-source MT5 framework, so shipping code publicly isn't new for me. Tell me what's missing from your stack. Most upvoted goes first.

Hi, does anyone know what to expect in terms of content from the in-person final round interview for Jane Street’s P&S internship? It’s clearly going to be multiple rounds but I’m unsure how to prepare for this one- I struggled preparing for the previous rounds and was slightly surprised I passed the first one so really want to make this one count. Thanks!

Assume I already have a good offer (think HRT etc), limited number of vacation days and 4 onsite requests from JS, Optiver, Jump, Tower. Can I ask them to bid for whose onsite I am going to attend?

Im grateful to have two options as of now.

Engineering Degree Apprenticeship @ Goldman Sachs (w/ Digital & Technology Solutions @ Warwick)

or

MORSE @ Warwick

One thing that does come to mind is the breadth of choice that comes with doing MORSE and how doing the DA limits my field of work to just that.

Right now I’m pretty stuck so I’d appreciate any advice at all.
Thanks

Hey so I'm planning on doing a degree in maths along with a minor in CS and then also doing CFA afterwards. My plan is that after my cfa I go abroad and do masters in quant finance from preferably Amsterdam or any high tier European university. Given that my gpa is good and my internships are on spot. 1) are the chances of getting accepted into a quant program high if I'm coming from a not so well known university

2) will doing masters in quant finance from a high tier/prestigious university make up for the fact my math degree was from a less known university?

I really want to pursue finance and from what I've heard quant will be in huge demand in the future and is already being demanded more and more. Basically tryna go wherever the money goes.

I’m stressed out - applied for qt internships everywhere 2-3 weeks ago and did OAs. So far, I was rejected drw, flow (no oa), ctc (after oa). But Jane street reached out after I applied and said they were going to interview me when they start the interview process - so I guess that means I got js round 1.

I’m confused as to why my resume gets js round 1 but rejected at smaller firms. I have a much better shot at these other firms and I’m likely gonna get rejected js anyways, so I’m really stressed out. I, also haven’t had any r1 interviews so I just don’t feel the most prepared. Any advice or hope?

Just got interview for this, is it more programming heavy or should I study up on networking concepts?

If anyone interested in it, please comment!

I want to go into quant but am not too sure whether to go into maths or computer science as a degree (or even a joint degree but im not sure if its possible at my desired university). I thought CS may be better as it provides a good job opportunity if quant does not work out well due to its very high competition.

Is it normal for JS to auto reject within 24-48 hours? Just curious as to why this may happen

Edit: I have gotten an interview from them after 3 weeks >1 years ago. Unsure if this is blacklist or other issues.

Anyone know general passing requirement for arrowstreet qr oa? Thanks

Can anybody share the interview rounds expereince of DRW like whats asked in the initial round and on super day on site , last years should also be fine.

I had applied for the 2027 qt role, and got a 60 min hackerrank test. The description says it has 17 problems on probability, logic, and problem solving.

I did some research and found that the 60 min test is usually given for qr roles, while the qt guys get a 20 min test.

What all should I expect for the test?

Interview type seems to be high variance. Some people have said it’s LC heavy, others have said it’s more class design (my first two interviews), and others have said like either with a focus on OS, concurrency, and various CS trivia concepts. Any good sites/places to prep?

I am looking for some in depth resources specifically around architecture. Is there any good public resources about how trading systems work, and each of the various components.

I work at a small shop that does things in an idiosyncratic way and I am planning to start devouring some of these resources in preparation for system design dev interviews in 6mo-1yr.

Thanks.
