Interview
Applied via my college's career website, received the interview 1 month later. The 3 interviewers were quite friendly, asked several questions in regard of machine learning algorithms and basic statistics. The machine learning questions were not the easiest one to answer, but they were really helpful in terms of giving me hints and assistance.
