went through the full loop last fall, chicago office, new grad SWE track. sharing because i couldn't find anything specific when i was prepping.
rounds: 1 phone screen with a recruiter (mostly resume, motivations, 20 min) 1 technical phone screen: 2 LC medium/hard problems, 45 min, no systems design onsite: 5 rounds back to back. two coding, one systems design, one CS fundamentals (OS, networking, concurrency), one "quantitative reasoning" which was probability and estimation problems, not pure algo
the systems design round was different than FAANG. they gave a trading-adjacent scenario: design a low-latency order routing system. they didn't care much about storage at scale. they cared about where the microseconds go and how you'd reduce them. if you've only done "design twitter" prep you'll feel it.
the quant round caught me off guard. stuff like: you have a biased coin, what's the expected number of flips to get two heads in a row? and conditional probability scenarios. i'm a CS person, not a math person, so i burned time on that one.
what mattered: every interviewer wanted you to narrate your thinking. silence is bad here. they'd let you dig a hole and then ask "is that the approach you want to commit to?" which is a hint if you catch it.
feedback loop was fast: got a call 4 days after the onsite. offer came with a tight deadline.
