Tldr:
Applying for 2027 internship roles at Citadel.

Studied Maths at a T20, got quite a lot of quant interviews from some companies like JS, Optiver etc, but not Citadel/Citsec.

Shit undergrad gpa, but 4.0 on my masters @ the same college. Will this hurt my chances?

So basically the title says it: I’m applying for the summer 27 roles @ Citadel, mainly focusing on research analyst roles (and possibly Trading at Citsec/Investment at HF).

When I applied for 2026 internships, I passed the filter for several well-known companies. Had interviews for JS, Optiver, Belvedere, SIG, Old Mission, several BBs, Blackrock, etc. Made it to several superdays, but it was very rough and I did not get much offers :( .

Now we’re back for round 2! Applying for the same companies, including the ones that autorejected me back then.

I’m having a ton of worries, because the previous interviews I’ve had in the past either did not need me to give my GPA, or at least asked for just “GPA” so I could give my major GPA instead. Citadel explicitly asks for “Overall GPA”, and unsurprisingly
I have never gotten a Citadel interview, not even an OA. I applied for pretty much every entry level QR, QT, Analyst and Equities role available at the time.

Now that I’m in my masters, and my performance has been pretty good, how much weight would be put onto the undergrad performance?

Additionally (this is very stupid), but will ATS order matter? Maybe I’m overthinking it, but will it make a difference if I list my undergrad as a second entry on the educations tab, so my achievements for grad school are on top? This is not my resume but the application portal at Citadel’s webpage.

Background:

Triple majored in Maths, Statistics, and Economics in undergrad. Without disclosing too much, got fucked over in my first two years because of health, mental health, and financials. GPA tanked like crazy after freshman year. Last few semesters are basically As and the occasional A-, with courses mostly in the 400s to 600 levels. GPA still is really subpar, (think 3.5-3.6 for major gpa, 3.3 overall).
Took a bunch of masters and PhD level coursework while in undergrad in maths and stats to make up for first and second year fuckups. Got As in pretty much every single one.

Got several quant competition 1st places in 2025-2026, and handful of research work in pure and applied maths. Also built a bunch of projects from sophomore - senior year, either trading related or work on state space models. Competed in IMC Prosperity (didn’t win, but at least we made it to the finals!). Professors were super kind to write me some killer recs. I’ve always loved school, but looking back at my freshman year does give me a lot of insecurities about myself.

Recently, I was accepted to a masters program in stats at the same school. All grad courses I’ve taken will transfer over and double count towards my masters GPA, which essentially makes it a 4.0. Courses are mainly in probability theory, machine learning, time series, adv. bayesian methods.

TLDR 2.0 :
NGMI or am I safe? :(

Any advice for the application process at Cit for equities or QR/QT? Thank you!!
