schedule phone interview, technical phone round. Indian interviewer with no manners to talk with the candidate, asking Java questions when candidate said comfortable with Python. The job description mentioned Java, or Python. The voice of the interviewer was unclear too.terrible experience

2 rounds interviews: one about java, oop, sql and technical background, another about data science in real-world user cases. Very practical questions and no need to crack leet code. Down to earth and of course very nice people!
