Interview was casual - it involved a phone screener, an online assessment (math questions, analytic scenarios), an in person interview with hiring manager (very conversational and around my background and knowledge)

I was set up for a 30 minute phone interview with a recruiter. It was a great conversation she told me about the company and let me ask questions. Very informative as well as casual. I was then setup with the team lead for the position for another phone interview. The phone interview were overall really great and helpful

I applied 12/27/2018 and was asked to take a neuroscience personality test( was actually pretty fun). 2 weeks later I was asked to do a phone interview with the recruiter. The next week I did 4 back to back 30 minute interviews at Nielsen to meet the team I'd potentially be on. 7 days later I received an offer.
