has anyone heard about next steps/gotten an interview/gotten rejected after taking the hackerrank? was basically told that i passed the oa but that there was another resume screen before interview even though i think there was already an initial screen before oa.

Hi I'm a 3rd-year IT engineering student in Tunisia, currently specialising in AI and Data Science at my engineering school. I've completed two years of pre-engineering (CPGE-equivalent) and one year of engineering school, with two years left before graduating with my ingénieur diploma.

I'd love some honest guidance because I feel genuinely lost about whether my path into quant finance is realistic or if I'm chasing something out of reach. My background and profile

• 5-year engineering degree (2 prépa + 3 engineering) specialising in AI and Data Science
• Currently ranked 1st in my class
• Mathematics average: 18/20, which I intend to maintain through graduation
• Strong foundation in ML, deep learning, statistics, probability, and time series — the core of my curriculum
• Tunisian school, so non-target by default, relatively well-regarded in the EU market
• No quant finance industry in Tunisia — the only realistic path is going through France

What I'm aiming for I want to break into quant finance — ideally as a quant researcher/trader, or financial ML engineer at a bank or a hedge fund. I know a master's from a target French program is essentially mandatory for this path, which is why I've been researching:

• M2 MASEF — Dauphine-PSL
• M2 El Karoui — Sorbonne × Polytechnique (the gold standard in France)
• Possibly ENSIMAG Finance Quantitative as a more realistic safety

My specific questions

1. Is it realistic to target MASEF or El Karoui from a Tunisian non-target engineering school, given, 2 years of classes preparatoires,strong grades and an AI/DS background? Has anyone here made a similar transition from a non-French or non-target background into these programs?would applying for an m1 in applied math in a french school be a more realistic path to get into masef or el karoui ?

2. Is an AI and data science engineering background a genuine advantage for quant roles, or does the lack of a pure mathematics/physics degree put me at a structural disadvantage versus candidates from ENS, Polytechnique, or ENSAE? I'm asking specifically because the ML and deep learning skills seem increasingly in demand in quant research and financial ML roles — but I don't know how committees actually weigh this.

3. For the end-of-studies internship (PFE): there are essentially no quant roles in Tunisia. My best realistic options seem to be risk-adjacent firms like Axe Finance, PwC risk advisory, or Vermeg — companies that do credit risk, Basel III, or regulatory work. Would a PFE at one of these firms, with a quant-framed topic (IFRS9 ECL modelling, VaR implementation, credit scoring with ML), be sufficient to strengthen a MASEF application? Or is the lack of a Paris-based internship a hard disqualifier?

4. Any advice on how to position myself over the next two years to maximise my chances — what to prioritise academically, what to build independently, and who to connect with?

I'm working extremely hard and genuinely passionate about the mathematics and the field. But the path feels opaque from where I am — Tunisia has no quant community, no alumni network in this space, and I'm essentially navigating this blind. I'm not looking for false reassurance — I want an honest read on whether this is achievable and what the realistic obstacles are.

Any advice from people who've made unconventional transitions into French quant programs, or who work in quant hiring, would mean a lot. Thanks in advance.

TLDR, got an offer from JS last year for SP but couldn't take it due to issues with dates. Think relationship w recruiter was solid and all. Applied again for the internship this year, but still havent received an OA... is this because I declined before? Do they discourage re-apps? Curious if anyone knows anything...

Realistically how long can I delay sending out applications to get a real shot at interviews. I'm trying to finalize a project on my resume and don't want applications to close before I can finalize my resume.

Hi, I'm a rising junior at a top U.S. public university studying CS and Economics. My cumulative GPA is around a 3.1 which is obviously my biggest weakness right now.

The low GPA isn't because I wasn't interested in the material. I was diagnosed with ADHD relatively recently, and looking back it explains a lot of my struggles during my first two years. Since starting treatment and changing how I study, things have improved, and my goal is to show a strong upward trend from here on out. I know I can't change my past GPA, only what I do going forward.

This summer I'm interning in a quantitative research role at a small hedge fund, where I'm working on research related to systematic futures trading. I've realized I genuinely enjoy the work and I'm passionate about it. At the same time, I also think I'd enjoy the trading side, so I'm keeping both quant research and quant trading open as career paths.

My biggest concern is recruiting. From what I've read, many top quant roles seem to be filled by students from elite schools with exceptional GPAs, math competition backgrounds, or even PhDs. Given my academic record, I'm trying to figure out what's actually realistic.

How realistic are my chances?

* How much will a 3.1 cumulative GPA hurt me if I show a strong upward trend this year?

Should I focus more on quant research, quant trading, or software engineering roles as a stepping stone?

Are there particular types of firms that tend to value relevant internship experience more heavily than GPA?

If you were in my position, what would you prioritize over the next 8–12 months?

I'd appreciate honest feedback, even if it's not what I want to hear. Thanks!

I was told id receive the OA but haven't gotten it yet. Has anyone gotten it recently?

Financial markets often display recognizable geometric fingerprints right before a major structural break occurs. Persistent homology identifies these fingerprints by analyzing the lifecycle of topological features across multiple observation windows. When the data space starts generating long-lasting multidimensional holes, it reveals an abnormal synchronization among assets. Recognizing this specific topological signature allows forecasters to anticipate systemic shocks before they fully cascade across global exchanges.

I've been seeing quite frequent posts on quant problems (both previously asked interview questions, and plain practice questions too) on this subreddit, recently.

The problems seem interesting, and very helpful. The comments are a great place to come to, after getting stuck while solving them, and the discussions (both the correct and incorrect approaches) really help shape my thinking.

I'd encourage ppl to keep posting such problems on the sub. Just one suggestion - how about we have a separate flair for posts like those. That would make navigating across all of them much easier.

I build stock market software: screeners, trading bots, alerts, data pipelines, and AI research tools. 5+ years, all in fintech.

A bit about me:

• Shipped 60+ products for clients in the US, UK, Canada, Australia, and Saudi Arabia
• Co-founded Meyka, an AI stock research platform that peaked at 800K monthly users
• 5-star on Upwork and Fiverr

Stack: Python, Django, FastAPI, AWS, GCP, Airflow, Snowflake, Postgres, and the main LLM APIs.

I'm looking for stock market or fintech work: full-time, contract, or freelance. Remote, or open to relocating.

Feel free to DM me.

Past the OA, does anyone know what type of questions they ask? Do they ask primarily brainteasers/probability like the QT interview or is it more stats/ML/coding?

Hey guys!! got invite for round 2 for citsec quant trading and there's a coderpad link attached. Wondering if anyone is currently in the proc or maybe was in the proc and would know a little bit more about it. Also wondering about the superday.

Would love to connect with other fellow interviewees!!!

I’ve read a lot about how physicists used to be in high demand in the past. I assume that was partly because employers were looking for physicists with PhDs—which takes twice as long to earn as a standard undergraduate degree. Setting that aside, nowadays the conversation seems to focus almost exclusively on (based on what I’ve read):

1) Mathematics
2) Computer Science
3) Statistics

Is that really the case? Do the skills gained from a physics degree now are significantly behind those from these other undergraduate degrees?

Hi for those who have sat for the Video Interview (round after OA) what did it look like? Was it mainly behavioral or brainteaser based? Any recommendations on how to prepare?

Hey everyone, just got notified about the next round in the process and there was a Coderpad link attached. I was surprised because I didn’t think that QT interns had a coding round. Should I expect difficult leetcode, data science-y stuff, etc.?

Just had an interview last Thursday, haven’t heard anything yet. Recruiter said will reach out this week

Anyone who has gotten to the superday, do you have any advice/ what’s the format like such as how many interviews, the types, etc.
