Keep reaching final rounds but can't convert them into offers

I’m a 3rd yr B. Tech student currently applying for SWE internships. I’ve gone through 5+ serious interview processes and quite a few OAs, mostly for roles offering in fifties thousands.

The frustrating part is that I usually clear 2–3 interview rounds and make it to the final stage, but somehow fail to convert it into an offer.

For context, I’m ~1500 on Codeforces, ~1800 on CodeChef, 1800+ on LeetCode, have solved a lot of DSA/CP problems, and have built 3–4 solid projects around systems, backend and infrastructure.

I also recently interviewed with an HFT firm but haven’t received an update for almost a month. I have another MFT opportunity, but the compensation is significantly lower, so I’m unsure whether to take it or keep looking.

I know I need to keep trying, but constantly getting this close and failing at the end is exhausting. What am I missing? For people who’ve been in a similar situation, what helped you finally convert interviews into offers?

Anyone experienced a long wait after an HFT C++ Developer interview?

I interviewed for a C++ Developer position at an HFT/trading firm about a month ago. I completed all the interview rounds, and since then I haven't received any updates no offer, no rejection, and no request for additional interviews.

I also sent a polite follow-up email about two weeks ago but haven't received a response.

I'm curious if this is common in the HFT industry. Has anyone here experienced a similar delay and still ended up receiving an offer, or is a month of silence generally a sign that I've been rejected?

I'd really appreciate hearing about your experiences, especially how long it took you to hear back after your final interview.

Would you accept an unpaid C++ systems role at an MFT startup?

I'm a 3rd-year CS undergraduate. I recently spoke with the founder of an MFT (Market Making/Trading) startup after they saw my C++ low-latency systems project.

They want me to help build parts of their C++ low-latency backend, but the role is completely unpaid (around 2–3 hours/day).

Do you think it's worth taking for the learning and experience, or should I only consider it if there's a clear path to a paid internship/contract?

Would love to hear from people who've worked in C++, HFT/MFT, or startup infrastructure.

Build a c++ project for fun and ended up getting feedback from IMC TRADING and other hft employees.

A few months ago I was just grinding on CF, and preparing for SWE internships like most students.

Then I got curious about low-latency systems and HFT infrastructure. I had no finance background, no internship experience, and definitely wasn't expecting anything to come out of it.

So I started building a project called **Pulse-Order**.

It's a C++20 project where I tried to simulate parts of a low-latency trading system:

* Binary market data packets

* L2 order book

* Order matching logic

* Risk checks

* DPDK-based packet processing

* Performance benchmarking

I put the code on GitHub and shared some progress online.

Ps: (I took help from Chatgpt ai(web version) not any agentic ai or claude

The surprising part?

People working in HFT and trading infrastructure actually started responding. I got feedback from engineers associated with firms like IMC Trading, Jane Street, and other low-latency/HFT backgrounds. Some pointed out flaws, some suggested improvements, and some were genuinely encouraging.

It was honestly unexpected.

The biggest lesson for me:

Trying to build something slightly beyond your current skill level teaches far more than following tutorials. The project may be unfinished, but the learning and connections that come from it are very real.

The project is nowhere near production-ready, but it taught me more about networking, performance, Linux, memory layout, and modern C++ than months of tutorial watching.

Curious if anyone else here has had similar experiences where a side project unexpectedly connected them with industry professionals.

Launching version 2 soon .....

hardest contest:(

Literally I was able to solve only A and B .

C is a Bit manipulation question already given up..

(I am sure I will get -100 delta)

As a student from a non-IIT background, that was honestly unexpected.

Huge Respect to Every Codeforces Candidate Master, IM, and LGM

https://preview.redd.it/vac2wa24vuah1.png?width=379&format=png&auto=webp&s=aa3b304c650f7a4d8cddd579e40e940f1d974d21

Today was one of those days that reminds me how much there is to learn in competitive programming.

I picked an 1800-rated Codeforces DP problem and spent nearly 2 hours trying to solve it.

Instead of following the obvious DP direction, I convinced myself there had to be a greedy solution. I built one, debugged it carefully, and for a moment I thought I had found a beautiful shortcut.

Then came Wrong Answer on test #12.

I kept trying. I discussed different ideas with ChatGPT, refined the approach multiple times, and even those versions eventually failed on hidden tests.

Finally, I opened the editorial.

Within a few minutes, I understood why my intuition was wrong. It wasn't a small bug it was the entire approach. The official solution relied on an insight I simply hadn't seen..

And every time this happens, my respect for Codeforces Candidate Masters, International Masters, and Legendary Grandmasters grows even more. Solving these problems consistently during contests is an incredible skill.

One problem defeated me today.

Hopefully, it also made me a little stronger for tomorrow.
