I applied through a friend who works at Unity, They called me back about 3 weeks later. The overall process was 6-7 interviews, two technical and four personal. First interview - A phone call with HR. Second Interview - A short Zoom meeting with the direct manager. Third Interview - A case study at the office with the direct manager. Fourth Interview/Test - A home assignment to test your analytical skills. Fifth Interview - Presentation of your work to three employees. Sixth Interview - A personal at the office meeting with the head of the department. Seventh Interview - HR interview. It took around a month and a half, maybe two months overall (pretty quick regarding the number of interviews)
