Phone interview with HR, the call lasts about 15 minutes. Several questions about background and past experiences related to data analysis. Two questions about future plans. Ended with me asking questions about the role, length of projects etc. The graduate programme is an one-year programme including two half-year rotations with different groups (data scientists, business team etc.) in Booking. The average length of the project is about one-month. The interviewer said the position is really competitive and the result for my interview came out in the next two days.
