First assignment and second assignment was based on a dataset provided by them. You need to answer few questions based on the dataset. Third round is the Interview. Interview was the most unprofessional part. Interview ends based on the interviewer’s discretion i.e. if the interviewer finds your answers unsatisfactory they will immediately end the interview. Interviewer will also ask vague questions and expect very specific answers. Other answers have no room. You also need to know everything about the company before the interview as they ask questions about the history and future of the company.
