They have multiple rounds that they do not provide information on in the beginning. The first round was with the hiring manager. He asked about the background and relevant questions around the same. The next 2 rounds were for ML and coding. In Coding round, the person asked me ML- gave a jupyter like notebook and asked to make edits and do some initial analysis. In the Ml round the interviewer asked about coding. Asked to write code for 2 leetcode medium/ easy problems and 1 SQL problem in 1 hour. So they were mixed up about the ML and coding round.

First interview with their CTO, then 2 rounds of interview with two data scientists. 2nd round focused on previous projects and coding. The third round was on previous projects and questions on machine learning. Then they rejected with an auto-generated email. After that there would have been another 4 rounds of interviews as per prior communication. The interviewers are not organized at well. First they said after CTO round there will be a coding and then virtual onsite. But a third round popped up. Initially they told the third round would be coding +ML and later said only ML. The interview was scheduled for 1 hr but continued for 80+ minutes. The interviewer was not sure about what to ask. They asks a lot of question from their projects and can't explain. The interviewers are inexperienced. Total waste of time and effort.
