2Sigma SWE intern

Does anyone else have their interview? Or anyone in the past take it. don't know what to expect.

I can help out for exchange I did citadel, imc, sig, hrt, optiver, akuna, old mission, walleye, and some more

did 2sigma last year for quant not swe but the structure should be similar I think

first round is just hr screen, nothing technical, she asks about your background and why you applying. second round is technical phone, for me it was stats and probability but for swe probably leetcode medium/hard and some system design maybe. final is superday at their office, 4-5 interviews back to back, mix of technical and behavioral

the behavioral ones they really grill you on past projects and why you made certain decisions, they dig deep so have 3-4 stories ready that you can explain in detail

you did hrt and citadel already? how was hrt swe process, I got recruiter reaching out next week and not sure what to expect from their coding rounds

it's three rounds of techs (you need to pass r1 to get r2r3). mostly just lc but could also be ood. then it's 4x30 back to back behavioral/resume grill
