There are about three rounds. First round was a chat with recruiter. Follow by a technical interview and a coding challenge. I was schedule for the final round, but the interviewers cancel the interview one hour before the meeting without any reasons. I follow up and they promise to reschedule, but never did. Two week later, got a rejection email saying, "Thank You for interviewing with us for the final round". Which is a complete lie and wasted my time. Their HR really need to be more organized.
