Perguntas de entrevista de vagas de Software Engineer (Data) da empresa Yelp

The interview had 3 phases: HR call, non-technical 45 min call, then a technical 3h30 call. The technical phase consisted in two 40 min code exercises, one system design and one values interview. Interviewers were nice and everything went well, it took me some time to understand the first coding exercise, but with some hints I was able to solve it. They took a week to look for a place for me and in the end they said they couldn't find anything. No feedback was given.
