Coupang's engineering loop is heavily concentrated in its Bangalore office and is unusually long (candidates report 2-3 month timelines). A typical Senior/Staff SE loop runs 4-6 rounds: a phone screen (DSA), one or two coding rounds (LC-medium/hard, often graph/matrix/DP with an ask for asymptotically-optimal working code), a machine-coding LLD (2-hour laptop build of a small OOP service), a HLD system-design round, plus one or two behavioural rounds with the hiring manager and a bar-raiser. Coupang uses Amazon-style Leadership-Principle probing in the behavioural loops, and multiple candidates flag ghosting after onsites and a director/VP culture-fit final round.
These 18 writeups cover software engineering roles. All of them were posted under a forum handle, so we could not verify the authors’ identities.
