I had 4 interviews total over a 3 month period. First was with a phone interview with a Nielsen recruiter. I has to take an online timed assessment and pass to continue on. The assessment contained questions about my personality and problem solving skills/abilities. Second was a phone interview with a manager two weeks after the first. Third was an in person interview with the manager from the second phone interview and another manager. It was about 1.5 weeks after the second interview. The fourth and final interview was a month after the third. I met with the director of the Center of Excellence.
