CME Group Software Engineering Intern interview questions

cold applied online->auto OA(two LC easy, very free)->hr call(not standard i think, i was moved into a more competitive pipeline running a yearlong program after the summer)->1hr first round tech (lc standard)->final round 15 min behavorial + 1hr sys desgin->offer! interview breakdowns: both on glider like the OA, glider sucks so prepare for inevitable technical difficulties (one of my interviewers kept getting logged out at random) round 1: LC easy (finished in 5 min)-array basics; choose java or python btw round 2: 15 min behavorial: with HR, v standard, why CME?, why this position? what wud u do in X scenario? 1hr sys design: so this one was a little weird ngl, problem brief itself was very standard: design uber but they operated in a very non-standard way in which on top of the schema sketch they wanted significant depth on the APIs included as well as identifying every field, primary key, and for each field: the type (ie. VARCHAR (<255) for every. single. field. in. every. single. sql. table. so be prepared for that. they also asked me to draw out the UI lol? using the glider platform (think of using MS Paint shapes to draw smth but more scuffed); the interviewer was really kind and very accommodating with glider difficulties and will also nudge you in the right direction if you are hesitant in your implementation scheduled hr feedback call on resume as well and these r notes: all cme resumes are apparently reviewed by humans! (they don't rely on ats :0), skills section right after education, demonstrate depth in one field but include non-domain extracurriculars of your non-academic passions to make you memorable, MUST include dates for projects even tho glider sucks, all the humans i interacted with were great so overall, positive exp, HR also accommodated rescheduling very well
