The whole process took one day. I applied through campus. Only those were asked to go for first round who are shortlisted on the basis of resume attached with one pager describing why we want to join the company. The process consists of two rounds (they took three rounds of some of the students including me). First round was simple quantitative aptitude, data interpretation questions and 3-4 ML questions. Second was technical round where they asked about resume, internships and some puzzles also about the one-pager that I have submitted before. Third round was technical cum hr where the interviewer has given me two business problem along with some resume and language (German) based questions. Finally the result was announced and I got selected.
