Entrevista
There are three rounds of interviews. The first is a non-technical interview with a manager. The second is a presentation about a past project. The third contains SQL, behavioral, data science design. Difficulty in general is ok.
Take home task and then interviews with employees. Straightforward interviews - behavioral, data cleaning, machine learning, SQL coding test (no probability or stats). Focused more on details of the actual data manipulation than other firms. Felt like they were looking for a person of a specific background
