The process only takes two weeks, it's quite efficient. The HR called to me and arranged the first round of interview with two different managers and also told me what should I prepare which was focusing on resume and personal experience. One day later, HR called me and told me there was positive feedback from interviewers, then he arranged the second round three days after. During the second round, it was much more specific on your own skills and understanding of data, at the meantime, I also showed my portfolio of the dashboard to my interviewer, it's a good thing that you might do it during your interview. Two days after, HR sent me an official offer letter and provided a wonderful package. This all process is really impressive and highly efficient and everything is clear that you won't feel confused.
