I applied in-person. The process took 3 weeks. I interviewed at Coupang (Seattle, WA) in Dec 2019
Interview
Overall very pleasant, but interviewers showed up late. Spent a lot time discussing their needs, timeline, team structure. etc, plus one algorithm question and a few design question. Questions are in general quite easy.
Interview questions [1]
